Unauthenticated network attack (AV:N/PR:N/UI:N) but exploitation depends on non-default server config, so AC:H; primary impact is arbitrary file disclosure (C:H) with no confirmed integrity/availability effect.
Primary rating from Vendor (VulnCheck).

Cockpit CMS before release 364 contains a path traversal and local file inclusion vulnerability that allows unauthenticated attackers to read arbitrary files or execute PHP files by including unvalidated PATH_INFO derived from REQUEST_URI in filesystem path construction without containment checks. Attackers can inject dot-dot sequences into the URL to traverse outside the designated spaces directory, and when the resolved path ends with a .php extension, the application passes it to include(), enabling local file inclusion on deployments using the PHP built-in server or certain non-default Nginx configurations.

AnalysisAI
Arbitrary file disclosure and PHP local file inclusion in Cockpit CMS before release 364 lets unauthenticated remote attackers read files outside the web root and, on certain server setups, cause the application to include() attacker-chosen .php files. The flaw stems from unvalidated PATH_INFO (derived from REQUEST_URI) being used to build filesystem paths without containment checks. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires that the Cockpit CMS deployment expose index.php via the PHP built-in server OR a non-default Nginx configuration that forwards unsanitized PATH_INFO/REQUEST_URI into the application - this is the explicit prerequisite from the description and the reason CVSS 4.0 sets AT:P. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor CVSS 4.0 score is 8.2 (High) with vector AV:N/AC:L/AT:P/PR:N/UI:N and confidentiality-only impact (VC:H, VI:N, VA:N), meaning the assessors rated this primarily as unauthenticated remote file disclosure rather than full code execution - LFI here includes existing .php files, not attacker-uploaded code, so it lacks a straightforward RCE integrity/availability impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker enumerates an internet-exposed Cockpit CMS instance and sends a crafted request to index.php with dot-dot sequences in the trailing path (PATH_INFO), traversing out of the spaces directory to read sensitive files such as configuration or credential files. Where the deployment routes PATH_INFO into the app and the resolved path ends in .php, the attacker points include() at an existing server-side PHP file to trigger local file inclusion; public exploit code for this technique already exists, lowering the skill needed. |
| Remediation | Vendor-released patch: upgrade to Cockpit CMS release 364 or later (https://github.com/cockpit-project/cockpit/releases/tag/364), which adds containment checks on the PATH_INFO-derived path. … Detailed patch versions, workarounds, and compensating controls in full report. |
