CVE-2024-35371 identifies a vulnerability in Ant Media Server version 2.8.2 related to improper output neutralization for logs, categorized under CWE-125. The root cause is insufficient input sanitization within the server's logging mechanism, which allows user-controllable data—such as identifiers or other potentially sensitive information—to be recorded in log files without adequate filtering or validation. This flaw can lead to the exposure of sensitive data through logs, which are often accessible to administrators or other system components. The vulnerability has a CVSS 3.1 base score of 7.5, reflecting a high severity primarily due to its impact on confidentiality (high), with no impact on integrity or availability. The attack vector is network-based (AV:N), requiring no privileges (PR:N) or user interaction (UI:N), making it relatively easy to exploit remotely. The scope remains unchanged (S:U), meaning the vulnerability affects only the vulnerable component. Although no known exploits have been reported in the wild, the potential for sensitive information leakage makes this a significant concern for organizations relying on Ant Media Server for streaming or media delivery. The lack of published patches necessitates immediate interim mitigation strategies to reduce risk.

The primary impact of CVE-2024-35371 is the unauthorized disclosure of sensitive information through log files. Since logs may contain identifiers, user data, or other confidential information, improper sanitization can lead to leakage of such data to unauthorized parties who gain access to logs. This can facilitate further attacks such as social engineering, credential theft, or targeted exploitation based on exposed information. The vulnerability does not affect system integrity or availability directly but compromises confidentiality, which can have severe consequences for privacy and compliance. Organizations worldwide using Ant Media Server v2.8.2 in production environments—especially those handling sensitive or regulated data—face increased risk of data breaches. The ease of exploitation without authentication or user interaction increases the threat level, potentially allowing remote attackers to inject malicious or sensitive data into logs. This can also complicate forensic investigations and incident response if logs are manipulated or contain misleading information.

Until an official patch is released, organizations should implement several specific mitigations: 1) Restrict access to log files strictly to trusted administrators and systems to minimize exposure of sensitive logged data. 2) Implement network-level controls such as firewalls and segmentation to limit exposure of Ant Media Server instances to untrusted networks. 3) Employ input validation and sanitization at the application or proxy level where possible to filter or neutralize potentially malicious or sensitive data before it reaches the logging mechanism. 4) Monitor logs for unusual or suspicious entries that may indicate exploitation attempts or injection of malicious content. 5) Consider disabling or reducing logging verbosity temporarily if feasible, to limit sensitive data capture. 6) Prepare for rapid deployment of official patches by maintaining up-to-date asset inventories and patch management processes. 7) Conduct security awareness training for administrators on the risks of log exposure and best practices for secure log management. These targeted actions go beyond generic advice by focusing on controlling log data exposure and proactively filtering inputs.
