EUVDB-ID: #VU43976

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2012-2668

CWE-ID:

Exploit availability:

Description

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

libraries/libldap/tls_m.c in OpenLDAP, possibly 2.4.31 and earlier, when using the Mozilla NSS backend, always uses the default cipher suite even when TLSCipherSuite is set, which might cause OpenLDAP to use weaker ciphers than intended and make it easier for remote attackers to obtain sensitive information.

Mitigation

Install update from vendor's website.

Vulnerable software versions

OpenLDAP: 2.4.6 - 2.4.30

Fixed software versions
