Description

This security bulletin contains information about 1 vulnerability.


1) Improper Authentication (CVE-ID: CVE-2012-4545)

CWE-ID: CWE-287 - Improper Authentication

CVSSv4: 6.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

The http_negotiate_create_context function in protocol/http/http_negotiate.c in ELinks 0.12 before 0.12pre6, when using HTTP Negotiate or GSS-Negotiate authentication, delegates user credentials through GSSAPI, which allows remote servers to authenticate as the client via the delegated credentials.
