High
| Vector | AV:N/AC:M/Au:N/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
CPAN version 2.28
Description
The issue is related to the incorrect verification of cryptographic signatures in the CPAN language, specifically in the
Module::Signature:: verify() function. This could allow a remote attacker to access confidential data, compromise its integrity, and cause a denial of service. The estimated number of potentially affected devices worldwide is not specified. There is no information about real-world incidents where this issue was exploited.Recommendations
For CPAN version 2.28, consider disabling the
Module::Signature:: verify() function as a temporary workaround until a patch is available. Restrict access to sensitive data and modules that rely on cryptographic signature verification to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
