Mitigating Controls (NIST 800-53 r5)AI
Directly addresses the CVE by requiring timely patching to version 8.2.6.4, which fixes the path traversal vulnerability in the haproxy_section_save interface.
Requires validation of inputs to the haproxy_section_save interface, preventing path traversal attacks that enable arbitrary file writes to scheduled tasks.
Enforces access controls on the web interface to block unauthenticated remote exploitation of the haproxy_section_save vulnerability.
Security SummaryAI
CVE-2026-33076 is a path traversal vulnerability (CWE-22) in the haproxy_section_save interface of Roxy-WI, a web interface for managing HAProxy, Nginx, Apache, and Keepalived servers. Affecting versions prior to 8.2.6.4, the flaw allows attackers to write arbitrary files into scheduled tasks, potentially leading to remote code execution. The vulnerability carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating critical severity due to its high impact on confidentiality, integrity, and availability.
The vulnerability can be exploited remotely over the network by unauthenticated attackers with no privileges or user interaction required. Successful exploitation enables full remote code execution on the affected Roxy-WI server, allowing attackers to execute arbitrary commands, potentially compromising the managed load balancers and web servers.
Mitigation is available in Roxy-WI version 8.2.6.4, which addresses the issue through a specific commit. Security practitioners should upgrade to this patched version immediately. Relevant advisories and the fixing commit are detailed in the GitHub security advisory GHSA-mmgm-p9x9-h33j and commit aecc7971959092fa93e93531f1ffcde33524b031.
