DescriptionNVD

Silverpeas through 6.4.6 mishandles the "Personal space" feature that is selected when no componentId is set.

AnalysisAI

Absolute path traversal (CWE-36) in Silverpeas through 6.4.6 allows authenticated remote users to read arbitrary files from the server filesystem by exploiting the 'Personal space' fallback path in the FileServer servlet, activated when no componentId parameter is supplied. The CVSS vector confirms network-reachable, low-complexity exploitation requiring only low-privilege credentials, with high confidentiality impact and no integrity or availability loss. …

Vulnerability AssessmentAI

Exploitation The attacker must be authenticated to Silverpeas with at least low-privilege credentials (confirmed by CVSS PR:L). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 6.5 score is well-supported by the vector AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N: network-reachable, trivially exploitable once authenticated, with high confidentiality impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An authenticated Silverpeas user sends a crafted HTTP GET request to the FileServer servlet omitting the ComponentId parameter, causing the server to enter the Personal space code path. The attacker supplies an absolute path or traversal sequence (e.g., ../../etc/passwd or an absolute filesystem path) in the SourceFile or Directory parameter, which FileServerUtils assembles into a raw filesystem path without sanitization. …
Remediation The upstream fix is available as commit caa6e6d1ac967ebd29b39e11c2ef5e7fd0047eec in the Silverpeas-Core GitHub repository (https://github.com/Silverpeas/Silverpeas-Core/commit/caa6e6d1ac967ebd29b39e11c2ef5e7fd0047eec); a specific released version number incorporating this fix has not been independently confirmed from available data (upstream fix available via commit; released patched version not independently confirmed). … Detailed patch versions, workarounds, and compensating controls in full report.
