Vulnerability from github

Published

Severity ?

5.8 (Medium) - CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:H/I:N/A:N

Summary

In RubyGem excon, interrupted Persistent Connections May Leak Response Data

Details

Impact

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.

Patches

The problem has been patched in 0.71.0, users should upgrade to this or a newer version (if one exists).

Workarounds

Users can workaround the problem by disabling persistent connections, though this may cause performance implications.

References

See the patch for further details.

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.
