Attack Vector: Network
Privileges Required: None
User Interaction: Required
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

ServerBuddy by PluginBuddy.Com | Up to 1.0.5

How the Exploit Works

The vulnerability arises from the improper handling of certain user inputs in the iThemes ServerBuddy plugin. A threat actor can create a specially crafted request, which, when executed by an authenticated user, can trigger the injection of malicious objects into the server. This object injection could allow the attacker to run arbitrary code or commands on the server, potentially leading to complete system compromise or data leakage.

Conceptual Example Code

A conceptual example of how this vulnerability might be exploited could look something like this:

POST /serverbuddy_endpoint HTTP/1.1
Host: vulnerablewebsite.com
Content-Type: application/json
Cookie: auth=<user's authentication cookie>
{
"malicious_object": "serialized_object_here"
}

In this example, the attacker sends a POST request to a vulnerable endpoint of the ServerBuddy plugin. The “malicious_object” in the request body is a serialized object, which is injected into the server when the request is processed.

Mitigation and Prevention

The best mitigation against this vulnerability is to apply the vendor-supplied patch. Owners of affected systems should update their ServerBuddy plugin to the latest version as soon as possible. In the meantime, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation method, potentially preventing the exploitation of this vulnerability. However, these should not be considered long-term solutions, as they may not be able to completely prevent all possible exploit attempts.

Vulnerability Summary

CVE ID: CVE-2025-8675
Severity: High (CVSS 8.8)
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: System compromise and potential data leakage

Affected Products

Product | Affected Versions

Drupal AI SEO Link Advisor | 0.0.0 before 1.0.6

How the Exploit Works

The Server-Side Request Forgery (SSRF) vulnerability in the Drupal AI SEO Link Advisor allows an attacker to make HTTP requests from the vulnerable server to another server, potentially within the same network. This gives them the ability to bypass network access controls and perform actions as if they were the server itself. This could lead to unauthorized actions such as data exfiltration, remote code execution, or even complete system compromise.

Conceptual Example Code

The following is a conceptual example of how this vulnerability might be exploited:

GET /?url=http://internal.victim.com HTTP/1.1
Host: vulnerable.example.com

In this example, the attacker sends a crafted GET request to the vulnerable server (`vulnerable.example.com`). The `url` parameter in the request specifies an internal resource (`internal.victim.com`) that the attacker wants the server to fetch. If the server is vulnerable to SSRF, it will fetch the resource and respond with its contents, potentially revealing sensitive internal information.

Mitigation Guidance

The most effective way to mitigate this vulnerability is to apply the vendor-supplied patch. For Drupal AI SEO Link Advisor, this means updating to version 1.0.6 or later. If a patch cannot be applied immediately, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used to block or alert on potential SSRF attempts. However, these are temporary measures and should not replace patching the software as soon as possible.

Severity: High (8.8 CVSS Score)
Attack Vector: Remote
Privileges Required: None
User Interaction: None
Impact: System compromise and data leakage

Affected Products

Product | Affected Versions

Tenda AC20 | 16.03.08.12

How the Exploit Works

The vulnerability lies in the manipulation of the ‘deviceList’ argument within the function sub_46A2AC of the file /goform/setMacFilterCfg. By sending specially crafted data, an attacker can trigger a stack-based buffer overflow. This overflow condition allows a remote attacker to overwrite the intended buffer boundaries, causing arbitrary code execution or altering the intended control flow of the program, thus potentially leading to system compromise or data leakage.

Conceptual Example Code

The following is a conceptual example of a malicious HTTP request that could be used to exploit the vulnerability:

POST /goform/setMacFilterCfg HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"deviceList": "AAAAA....[Long string of A's to cause buffer overflow]....AAAAA"
}

In this example, a long string of ‘A’s is used in the ‘deviceList’ value to cause the buffer overflow. This is a common technique in buffer overflow exploits, although actual attack payloads would likely contain machine code to be executed on the victim’s system.
Please note that this is a simplified example and real-world exploitation might require a more sophisticated approach.

Mitigation

Users are strongly advised to apply the vendor patch as soon as it becomes available. In the meantime, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) could be used to mitigate this vulnerability. These systems can help detect and block malicious activity, providing temporary relief from the threat. Properly configured, they can prevent the exploit from reaching the vulnerable system, thus reducing the risk of a successful attack.

Overview

This blog post provides an in-depth analysis of the critical vulnerability CVE-2025-9023, that affects Tenda AC7 and AC18 routers of specified versions. This vulnerability, linked to a buffer overflow issue, poses significant risks to personal and organizational data and network security. It primarily resides in the function formSetSchedLed of the file /goform/SetLEDCfg, with the manipulation of the ‘Time’ argument leading to this buffer overflow vulnerability.

User Interaction: None
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

Tenda AC7 | 15.03.05.19
Tenda AC18 | 15.03.06.44

How the Exploit Works

The exploit works by manipulating the ‘Time’ argument in the ‘formSetSchedLed’ function of the ‘/goform/SetLEDCfg’ file. This manipulation leads to a buffer overflow vulnerability. Buffer overflow occurs when more data is written to a buffer than it can handle, leading to the overwriting of adjacent memory spaces. In this case, the overflow can be exploited to execute arbitrary code or cause a denial of service, potentially leading to system compromise or data leakage.

Conceptual Example Code

Here’s a conceptual example illustrating how an attacker might exploit this vulnerability. This example uses a malicious HTTP POST request to manipulate the ‘Time’ argument:

POST /goform/SetLEDCfg HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "Time": "buffer_overflow_generating_input" }

In this example, the “buffer_overflow_generating_input” is a placeholder for the actual malicious payload that would cause buffer overflow.

Mitigation Guidance

Users of affected Tenda AC7 and AC18 versions are strongly advised to apply patches provided by the vendor as soon as possible. In cases where immediate patching is not feasible, implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure. These tools can help detect and block exploit attempts, providing an additional layer of protection against this vulnerability.

Vulnerability Summary

CVE ID: CVE-2025-53587
Severity: High (CVSS 8.8)
Attack Vector: Network
Privileges Required: None
User Interaction: Required
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

ApusTheme Findgo | n/a through 1.3.57

How the Exploit Works

The exploit takes advantage of the CSRF vulnerability in ApusTheme Findgo. CSRF attacks occur when a malicious website, email, or program causes a user’s web browser to perform an unwanted action on a trusted site for which the user is authenticated. In this case, the attacker can trick an unsuspecting user into executing unwanted actions on their website. The actions executed will be seen as requests coming from the user, and thereby have the privileges of the user, leading to potential system compromise or data leakage.

Conceptual Example Code

The following is a conceptual example of how the vulnerability might be exploited. This example depicts a malicious HTTP POST request:

POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_payload": "..." }

In this example, the “malicious_payload” represents the commands or actions that the attacker wants to execute on the vulnerable site. When a user unintentionally sends this request, it appears to the site as a legitimate request from the user, hence bypassing any access controls.

Potential Mitigation

The most effective mitigation for this vulnerability is to apply the vendor-supplied patch. If this is not immediately possible, a temporary mitigation can be accomplished by using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to monitor, detect, and block malicious CSRF requests. It is also recommended to employ good application development practices to prevent CSRF attacks, such as the use of anti-forgery tokens, and to update regularly to the latest software versions.

Overview

CVE-2025-8876 is a critical security vulnerability in N-able N-central that exposes systems to potential compromise or data leakage. This vulnerability originates from improper input validation within the software that, if exploited, allows an attacker to execute arbitrary operating system commands. This can lead to unauthorized access, manipulation of data, or even complete system takeovers. The vulnerability affects versions of N-central before 2025.3.1, and its significance is highlighted by a Common Vulnerability Scoring System (CVSS) severity score of 8.8, marking it as a high-risk issue that requires immediate attention.

Vulnerability Summary

Attack Vector: Network
Privileges Required: Low
User Interaction: None
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

N-able N-central | Before 2025.3.1

How the Exploit Works

The vulnerability revolves around improper input validation within N-able N-central. Due to this flaw, an attacker can inject malicious operating system commands into areas of the software where they are executed without proper sanitization. This leads to a situation known as OS command injection, where an attacker can execute arbitrary commands on the host operating system. The exploitation can be achieved remotely over the network, without the need for any user interaction, making it a highly exploitable and dangerous vulnerability.

Conceptual Example Code

While the specific exploitation details for CVE-2025-8876 are not publicly available, a conceptual example of an OS command injection vulnerability might resemble the following:

POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "target_command": "ping; rm -rf /" }

In this pseudocode example, the attacker sends a POST request to a vulnerable endpoint on the target system. The “target_command” field was intended to run a harmless command (`ping`), but due to inadequate input validation, the attacker is able to append a harmful command (`rm -rf /`) which could delete all files on the system.

Mitigation Guidance

The primary mitigation for this vulnerability is to apply the vendor-supplied patch, which addresses the vulnerability by correcting the input validation flaw. This patch is available for all N-able N-central versions from 2025.3.1 onwards. As a temporary mitigation, if patching is not immediately feasible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can help detect and block attempts to exploit this vulnerability. However, these measures do not fully eliminate the risk and should be complemented by applying the vendor patch as soon as possible.

Impact: Full system compromise, potential data leakage, remote access

Affected Products

Product | Affected Versions

KuWFi 4G AC900 LTE router | 1.0.13

How the Exploit Works

The exploit takes advantage of command injection vulnerability on the HTTP API endpoints /goform/formMultiApnSetting and /goform/atCmd. An attacker with authenticated access to the router’s API can inject shell metacharacters into parameters such as ‘pincode’ and ‘cmds. This allows the attacker to execute arbitrary OS commands with root privileges, leading to full system compromise, enabling remote access, and potentially leaking sensitive data.

Conceptual Example Code

This is a conceptual representation of how the vulnerability might be exploited. In this example, the attacker sends a malicious HTTP POST request to the /goform/atCmd endpoint:

POST /goform/atCmd HTTP/1.1
Host: router-ip
Content-Type: application/x-www-form-urlencoded
Cookie: sessionid=authenticated-session-id
pincode=1234; rm -rf /&
cmds=;telnetd&

In this hypothetical example, the attacker injects OS commands (`rm -rf /&` and `telnetd&`) into the ‘pincode’ and ‘cmds’ parameters. The former command can lead to deletion of all files in the system, while the latter command starts a telnet daemon, enabling remote access.

Mitigation

Users of the affected KuWFi 4G AC900 LTE router version are advised to immediately apply the vendor’s patch to fix this vulnerability. In situations where the patch cannot be immediately applied, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation. However, these are not long-term solutions and the patch should be applied as soon as possible to fully secure the system.
