CVE-2010-3901  (opens in a new tab)
CWE-20  (opens in a new tab)

How to fix?

Upgrade Debian:13 openconnect to version 2.25-0.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openconnect package and not the openconnect package as distributed by Debian. See How to fix? for Debian:13 relevant fixed versions and status.

OpenConnect before 2.25 does not properly validate X.509 certificates, which allows man-in-the-middle attackers to spoof arbitrary AnyConnect SSL VPN servers via a crafted server certificate that (1) does not correspond to the server hostname or (2) is presented in circumstances involving a missing --cafile configuration option.
