Positive Technologies (AI Summary)

CVSS v2.0

4.3

Medium

Base vector

AV:N/AC:M/Au:N/C:N/I:P/A:N

Name of the Vulnerable Software and Affected Versions: IO::Socket::SSL versions 1.14 through 1.25

Description: The certificate checking feature in IO::Socket::SSL has an issue where the verify hostname of cert function only matches the prefix of a hostname when no wildcard is used. This allows remote attackers to bypass the hostname check for a certificate.

Recommendations: For IO::Socket::SSL versions 1.14 through 1.25, consider updating to a version outside of this range to resolve the issue. As a temporary workaround, restrict the use of the verify hostname of cert function to minimize the risk of exploitation.
