F5 Networks BIG-IP : libcurl vulnerability (K52828640)

Medium Nessus Plugin ID 105441

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

A flaw was found in curl before version 7.51.0 When re-using a connection, curl was doing case insensitive comparisons of user name and password with the existing connections. This means that if an unused connection with proper credentials exists for a protocol that has connection-scoped credentials, an attacker can cause that connection to be reused if s/he knows the case-insensitive version of the correct password. (CVE-2016-8616)

Impact

An attacker can cause an unused connection with credentials to be reused if the attacker knows the case-insensitive version of the correct password. Local access to an affected F5 system is necessary to trigger the exploit from the affected F5 system.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K52828640.
