Unauthenticated Remote Code Execution in Roxy-WIGHSA-53r2-mq99-f532
CRITICALFix: hap-wi/roxy-wi@82666dfGHSA-53r2-mq99-f532 is a critical-severity (CVSS 10) OS Command Injection vulnerability. 3 public exploit references exist, so weaponization risk is real. A fix is available — see the affected versions and patch details below.
Exploitation Status
Proof-of-concept exploit code exists
- CISA’s SSVC triage found public proof-of-concept exploit code for this CVE, though no confirmed active exploitation.
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- A successful exploit gives an attacker total control of the affected component, not partial access.

Description
Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. Versions prior to 6.1.1.0 are subject to a remote code execution vulnerability. System commands can be run remotely via the subprocess_execute function without processing the inputs received from the user in the /app/options.py file. Attackers need not be authenticated to exploit this vulnerability. Users are advised to upgrade. There are no known workarounds for this vulnerability.
Affected Products
roxy-wiroxy-wiResearch use only. For defensive security, authorized penetration testing, and academic research only. Never execute exploit code against systems without explicit written authorization.

Detection & mitigation playbook
VulnerabilityDetect
Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).
Fix
Upgrade the affected component to the fixed release for GHSA-53r2-mq99-f532, or apply your distribution's backported patch — distro builds are often patched at an older version number, so check your vendor's advisory rather than the upstream version alone.
Workarounds
Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.
