AI Analysis
Technical Summary
CVE-2026-58179 is a stack-based buffer overflow vulnerability in the Apache Traffic Server's regex_remap plugin. The flaw occurs due to improper handling of substitution input, leading to stack overflow and integer overflow conditions. This vulnerability affects Apache Traffic Server versions 8.0.0 through 8.1.9, 9.0.0 through 9.2.14, and 10.0.0 through 10.1.3. The Apache Software Foundation has fixed this issue in versions 9.2.15 and 10.1.4. The CVSS v3.1 score is 8.1, indicating a high severity with network attack vector, high impact on confidentiality, integrity, and availability, and requiring no privileges or user interaction but with high attack complexity.
Potential Impact
Successful exploitation could allow an attacker to cause a stack-based buffer overflow, potentially leading to arbitrary code execution, denial of service, or other impacts affecting confidentiality, integrity, and availability of the affected system. The CVSS score of 8.1 reflects a high severity vulnerability with significant impact if exploited.
Mitigation Recommendations
Users should upgrade Apache Traffic Server to version 9.2.15 or 10.1.4 or later, as these versions contain fixes for this vulnerability. No other mitigation or temporary workaround is indicated. Patch status is confirmed by the vendor advisory recommending these upgrades.
