XWiki Platform: Path traversal via resources parameter in ssx and jsx endpoints when using leading slash

03 Exploitation and scoring

Exploitation
Assessed, none found. CISA's assessment recorded neither public exploit code nor evidence of exploitation when it was made.
SSVC decision
  • ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
  • AutomatableyesAn attacker can reliably automate reconnaissance through exploitation, so this scales.
  • Technical ImpactpartialSuccessful exploitation gives limited control of the vulnerable component.
CISA publishes the decision points, not a final SSVC decision. The decision also depends on mission and well-being impact, which is a property of your deployment rather than of the vulnerability.
EPSS probability
18.52% probability of exploitation activity in the next 30 days.
EPSS percentile
Equal to or higher than the score of 97.2% of scored records. A rank, not a probability.
NVD base score
9.3 (CVSS v4.0), scored by the NVD independently of the CNA.
