CVE-2026-25525: OpenMage LTS has a Path Traversal Filter Bypass in Dataflow Module
The Dataflow module in OpenMage LTS uses a weak blacklist filter (str_replace('../', '', $input)) to prevent path traversal attacks. This filter can be bypassed using patterns like ..././ or ....//, which after the replacement still result in ../. An authenticated administrator can exploit this to read arbitrary files from the server filesystem.
| Metric | Value | Justification |
|---|---|---|
| Attack Vector (AV) | Network | Exploitable via admin panel |
| Attack Complexity (AC) | Low | Simple bypass pattern |
| Privileges Required (PR) | High | Requires admin authentication |
| User Interaction (UI) | None | No additional user interaction needed |
| Scope (S) | Unchanged | Impacts the vulnerable component |
| Confidentiality (C) | High | Can read sensitive system files |
| Integrity (I) | None | Read-only vulnerability |
| Availability (A) | None | No impact on availability |
