A vulnerability classified as problematic was found in excon Gem up to 0.70.x on Ruby (Ruby Gem). This vulnerability affects an unknown code block of the component Persistent Connection Handler. The manipulation with an unknown input leads to a resource control vulnerability. The CWE definition for the vulnerability is CWE-664. The product does not maintain or incorrectly maintains control over a resource throughout its lifetime of creation, use, and release. As an impact it is known to affect confidentiality. CVE summarizes:
In 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.
The weakness was published 12/16/2019 (GitHub Repository). The advisory is available at github.com. This vulnerability was named CVE-2019-16779 since 09/24/2019. The exploitation appears to be difficult. The attack can be initiated remotely. The requirement for exploitation is a single authentication. Successful exploitation requires user interaction by the victim. The technical details are unknown and an exploit is not available.
Upgrading to version 0.71.0 eliminates this vulnerability.
