YouDataSum CPAS Audit Management System V4 Path Traversal via downPlugs fileId

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

YouDataSum CPAS Audit Management System V4 contains a path traversal vulnerability that allows unauthenticated attackers to read arbitrary files by manipulating the fileId parameter. Attackers can send GET requests to /cpasm4/plugInManController/downPlugs with ../ sequences in fileId to retrieve system files like /etc/passwd. Exploitation evidence was first observed by the Shadowserver Foundation on 2025-01-13.
