Rescana Cybersecurity Advisory Report: Apache Traffic Server Vulnerabilities
Executive Summary
Recent discoveries have unveiled critical vulnerabilities within Apache Traffic Server (ATS), identified by CVE-2024-38311, CVE-2024-56196, and CVE-2024-56202. These vulnerabilities encompass improper input validation, access control bypass, and expected behavior violations, predominantly affecting versions from 10.0.0 to 10.0.3. While there is currently no evidence of these vulnerabilities being exploited in the wild, they represent significant security risks that necessitate immediate attention and remediation.
Technical Information
The vulnerability CVE-2024-38311 arises due to improper input validation within Apache Traffic Server, potentially allowing attackers to perform request smuggling through pipelining after a malformed request. This flaw is prevalent in versions 10.0.0 to 10.0.3. Insights into this vulnerability can be accessed through the Apache mailing list here and further analysis provided by Cybersecurity News.
CVE-2024-56196 pertains to improper access control, stemming from incompatible Access Control List (ACL) behavior, thereby granting unauthorized access. This vulnerability affects the same versions as CVE-2024-38311. For a comprehensive understanding, refer to the Red Hat Customer Portal and RedPacket Security.
The vulnerability CVE-2024-56202 is linked to an expected behavior violation within Apache Traffic Server, creating opportunities for exploitation by malicious entities. This affects versions 9.0.0 through 9.2.8 and 10.0.0 through 10.0.3. Users are urged to upgrade to versions 9.2.9 or 10.0.4 or newer. Detailed advisories are available on OSV.dev and Vulert.
Exploitation in the Wild
Current assessments reveal no evidence of active exploitation of these vulnerabilities in the wild. However, the absence of exploitation does not mitigate the potential risks posed by these vulnerabilities. The CVE Exploit in the Wild Finder tool has confirmed the lack of active exploit reports for these CVEs, underscoring the critical need for preemptive measures to safeguard systems.
Mitigation Strategies
Organizations must prioritize upgrading affected systems to Apache Traffic Server versions 9.2.9 or 10.0.4 or newer to mitigate these vulnerabilities. Continuous monitoring of network traffic for anomalies remains essential to identify potential exploitation attempts. Furthermore, reinforcing ACL configurations will mitigate the risk of unauthorized access.
Conclusion
The vulnerabilities present in Apache Traffic Server highlight the imperative need for organizations to maintain robust security postures by implementing timely updates and vigilant monitoring. Proactive measures, informed by continuous threat intelligence, are crucial in mitigating potential exploitation risks.
