CVE-2026-58162: CWE-295 Improper Certificate Validation in Apache Software Foundation Apache Traffic Server
CVE-2026-58162 is a critical vulnerability in Apache Traffic Server affecting versions 8.0.0 through 8.1.9, 9.0.0 through 9.2.14, and 10.0.0 through 10.1.3. The issue arises from the certifier plugin generating certificates based on attacker-controlled client SNI, leading to improper certificate validation. This flaw can result in significant impacts including loss of confidentiality, integrity, and availability. Users are advised to upgrade to versions 9.2.15 or 10.1.4 where the issue is fixed.
AI Analysis
Technical Summary
The Apache Traffic Server certifier plugin improperly validates certificates by generating them based on client Server Name Indication (SNI) values that can be controlled by an attacker. 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 flaw is identified as CWE-295 (Improper Certificate Validation). It has a CVSS 3.1 base score of 10.0, indicating critical severity with network attack vector, no privileges or user interaction required, and impacts on confidentiality, integrity, and availability. The vendor has released fixed versions 9.2.15 and 10.1.4 to address this issue.
Potential Impact
Successful exploitation allows an attacker to generate certificates based on attacker-controlled client SNI, potentially enabling man-in-the-middle attacks, spoofing, or interception of secure communications. The CVSS score of 10.0 reflects critical impact on confidentiality, integrity, and availability without requiring privileges or user interaction.
Mitigation Recommendations
Users should upgrade affected Apache Traffic Server installations to version 9.2.15 or 10.1.4, which contain the official fixes for this vulnerability. No other mitigation or temporary workaround is indicated in the provided data.
