Vulnerability from github – Published: 2025-11-20 18:31 – Updated: 2025-11-20 18:31

Details

BASIS BBj versions prior to 25.00 contain a Jetty-served web endpoint that fails to properly validate or canonicalize input path segments. This allows unauthenticated directory traversal sequences to cause the server to read arbitrary system files accessible to the account running the service. Retrieved configuration artifacts may contain account credentials used for BBj Enterprise Manager; possession of these credentials enables administrative access and use of legitimate management functionality that can result in execution of system commands under the service account. Depending on the operating system and the privileges of the BBj service account, this issue may also allow access to other sensitive files on the host, including operating system or application data, potentially exposing additional confidential information.

Severity

9.3 (Critical)

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
