Vulnerability from github – Published: 2026-09-16 18:32 – Updated: 2026-09-16 18:32

Details

Scirius through 3.8.0 contains an arbitrary file write vulnerability in the PCAP filestore upload endpoint that allows default User role users to write attacker-controlled JSON content to filesystem paths. Attackers can supply path traversal sequences in the uploaded document's _id field to escape the intended directory and write files with .json extension to arbitrary locations as root.

Severity

8.1 (High)

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.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
