Summary

Duplicate Advisory: ssrfcheck has Incomplete IP Address Deny List that leads to Server-Side Request Forgery Vulnerability

Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-p4hc-9pjh-55c8. This link is maintained to preserve external references.

Original Description

Versions of the package ssrfcheck below 1.2.0 are vulnerable to Server-Side Request Forgery (SSRF) due to an incomplete denylist of IP address ranges. Specifically, the package fails to classify the reserved IP address space 224.0.0.0/4 (Multicast) as invalid. This oversight allows attackers to craft requests targeting these multicast addresses.

Severity

8.2 (High)

Detection rules are retrieved from Rulezet.

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.
