Detailsinfo

A vulnerability classified as critical has been found in CGit up to 0.11. This affects an unknown functionality of the file blob/cgit.c of the component ui-blob Handler. The manipulation of the argument mimetype with an unknown input leads to a crlf injection vulnerability. CWE is classifying the issue as CWE-93. The product uses CRLF (carriage return line feeds) as a special element, e.g. to separate lines or records, but it does not neutralize or incorrectly neutralizes CRLF sequences from inputs. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

CRLF injection vulnerability in the ui-blob handler in CGit before 0.12 allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks or cross-site scripting (XSS) attacks via CRLF sequences in the mimetype parameter, as demonstrated by a request to blob/cgit.c.

The weakness was presented 01/20/2016 (oss-sec). The advisory is shared at openwall.com. This vulnerability is uniquely identified as CVE-2016-1899 since 01/13/2016. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available.
