EXPLOIT

An Unauthenticated Arbitrary File Read vulnerability affects the
Agent when installed on a system. The parameter filename does not validate the
path thus allowing users to read arbitrary files. As
the application runs with the highest privileges (root/NT_AUTHORITY SYSTEM)
by default attackers are able to obtain sensitive information.

This issue affects Avid NEXIS E-series: before 2025.5.1; Avid NEXIS F-series: before 2025.5.1; Avid NEXIS PRO+: before 2025.5.1; System Director Appliance (SDA+): before 2025.5.1.

• → Look for HTTP requests to the /logs endpoint with a filename parameter containing path traversal sequences (e.g., %2F, %5C, ../) — this is the vulnerable parameter enabling arbitrary file read. ↗
• → Responses from the vulnerable Avid NEXIS Agent will include the 'gSOAP' string in the HTTP response header — use this to fingerprint the service. ↗
• → Use FOFA or similar asset discovery with the query body="Avid Nexis" to identify exposed Avid NEXIS Agent instances on the internet. ↗
• → No authentication is required to exploit this vulnerability — any unauthenticated GET request to /logs?filename= with an arbitrary path is sufficient. ↗

• · The vulnerability affects Avid NEXIS Agent running as root (Linux) or NT_AUTHORITY SYSTEM (Windows) by default, meaning file reads are not restricted by OS-level permissions. ↗
• · All affected product lines (E-series, F-series, PRO+, SDA+) share the same vulnerable Agent component and endpoint — detections should not be scoped to a single product variant. ↗
