The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
Rsyslog is a rocket-fast system for log processing. From versions 1.15.0 to 8.2610.0, rsyslog's omfile dynaFile facility intentionally allows templates to generate flexible output paths. This supports valid deployments that route logs into different directories or use dynamically generated file names. A deployment becomes unsafe when a dynaFile template uses a value influenced by untrusted input as a path component without explicit secure-path handling. In that configuration, the rendered path can escape the operator's intended log directory. This is not limited to the RFC5424 HOSTNAME field. Any untrusted value that reaches a dynaFile path component can create the condition. At time of publication, there are no publicly available patches.
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.
Penta Security WAPPLES 4.0.54.1, 5.0, and 6.0 contains a path traversal vulnerability that allows authenticated attackers to download arbitrary files via the name parameter of /webapi/file/transfer. Attackers can send GET requests with type=db_backup and ../ sequences in name to read files like /etc/passwd, and a hardcoded systemi account makes authentication effectively trivial. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-19.
