Detailsinfo

A vulnerability has been found in Vim tar.vim up to V.22 (Word Processing Software) and classified as very critical. This vulnerability affects the function shellescape of the component Mapping. The manipulation with an unknown input leads to a os command injection vulnerability. The CWE definition for the vulnerability is CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

The shellescape function in Vim 7.0 through 7.2, including 7.2a.10, allows user-assisted attackers to execute arbitrary code via the "!" (exclamation point) shell metacharacter in (1) the filename of a tar archive and possibly (2) the filename of the first file in a tar archive, which is not properly handled by the VIM TAR plugin (tar.vim) v.10 through v.22, as demonstrated by the shellescape, tarplugin.v2, tarplugin, and tarplugin.updated test cases. NOTE: this issue reportedly exists because of an incomplete fix for CVE-2008-2712. NOTE: this issue has the same root cause as CVE-2008-3075. NOTE: due to the complexity of the associated disclosures and the incomplete information related to them, there may be inaccuracies in this CVE description and in external mappings to this identifier.
