    Affected Products

    Product | Affected Versions

    Realtek Bluetooth HCI Adaptor | All Versions

    How the Exploit Works

    An attacker with regular user privileges can exploit this vulnerability by creating a symbolic link with the same name as a specific file in the system. This causes the system to delete arbitrary files pointed to by the link. Following this, the attacker can leverage the arbitrary file deletion to escalate their privileges within the system, potentially leading to system compromise or leakage of sensitive data.

    Conceptual Example Code

    Consider the following conceptual command-line interface (CLI) example, which demonstrates how an attacker could potentially exploit this vulnerability:

    # Attacker creates a symbolic link to a critical system file
    ln -s /etc/passwd ./vulnerable_file
    # When the system interacts with the 'vulnerable_file', it's in fact interacting with the /etc/passwd file
    rm ./vulnerable_file

    In this example, the attacker has created a symbolic link to a critical system file (‘/etc/passwd’). When the system attempts to delete the ‘vulnerable_file’, it will actually delete the ‘/etc/passwd’ file, potentially disrupting system operations and allowing the attacker to escalate their privileges.

    Recommended Mitigation

    Users are advised to apply the vendor-provided patch as soon as possible to mitigate this vulnerability. In cases where immediate patching is not feasible, implementing Web Application Firewall (WAF) or Intrusion Detection Systems (IDS) can provide temporary mitigation. These systems can monitor for suspicious activities and block malicious traffic, preventing exploitation of this vulnerability.

  • CVE-2025-32801: Kea Configuration and API Directives Vulnerability

    Overview

    The CVE-2025-32801 vulnerability is a significant cybersecurity threat that exposes systems running Kea versions 2.4.0 through 2.4.1, 2.6.0 through 2.6.2, and 2.7.0 through 2.7.8 to potential compromise or data leakage. This vulnerability is caused by the ability of Kea configuration and API directives to load a malicious hook library. Many systems currently in operation run Kea as root and leave the API entry points unsecured by default – a dangerous practice that inadvertently increases the severity of this vulnerability.

    Vulnerability Summary

    CVE ID: CVE-2025-32801
    Severity: High (7.8 CVSS score)
    Attack Vector: Network
    Privileges Required: None
    User Interaction: None
    Impact: Potential system compromise or data leakage

    Affected Products

    Product | Affected Versions

    Kea | 2.4.0 – 2.4.1
    Kea | 2.6.0 – 2.6.2
    Kea | 2.7.0 – 2.7.8

    How the Exploit Works

    The exploit takes advantage of Kea’s default settings, which leave API entry points unsecured. An attacker can use these directives to load a malicious hook library into the system. This is particularly dangerous in cases where Kea runs as root, as it allows the attacker to gain system-level privileges and potentially compromise the system or leak sensitive data.

    Conceptual Example Code

    Here’s a simplified conceptual example of how this vulnerability might be exploited. Please note that this is pseudocode and not meant to be run in a real environment.

    # Define malicious hook library
    malicious_hook = "malicious_library.so"
    # Define Kea API entry point
    kea_api_entry = "/var/kea/api/socket"
    # Load malicious hook library
    load_library(kea_api_entry, malicious_hook)
    # Execute malicious actions with root privileges
    execute_malicious_actions()

    In this example, the `load_library` function represents the abuse of Kea configuration and API directives to inject a malicious library. The `execute_malicious_actions` function then represents the actions an attacker might take once they’ve gained system-level privileges, such as exfiltrating sensitive data or installing additional malware.

    Countermeasures

    To mitigate the risk posed by this vulnerability, users are 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) can be used as temporary mitigation. Additionally, system administrators should consider reviewing and tightening security settings related to Kea’s operation, including running Kea with lower privileges and securing API entry points.
