VAR-201912-1836
Vulnerability from variot - Updated: 2023-12-18 12:17In RubyGem excon before 0.71.0, there was a race condition around persistent connections, where a connection which is interrupted (such as by a timeout) would leave data on the socket. Subsequent requests would then read this data, returning content from the previous response. The race condition window appears to be short, and it would be difficult to purposefully exploit this. RubyGem excon Contains an input validation vulnerability.Information may be obtained. RubyGem excon is an HTTP server for Ruby applications.
There are security vulnerabilities in RubyGem excon versions prior to 0.71.0. An attacker could use this vulnerability to leak information

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.
