GLSA-201709-09 : Subversion: Arbitrary code execution
High Nessus Plugin ID 103277
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-201709-09 (Subversion: Arbitrary code execution)
Specially crafted ‘ssh://...’ URLs may allow the owner of the repository to execute arbitrary commands on client’s machine if those commands are already installed on the client’s system. This is especially dangerous when the third-party repository has one or more submodules with specially crafted ‘ssh://...’ URLs. Each time the repository is recursively cloned or submodules are updated the payload will be triggered.
A remote attacker, by enticing a user to clone a specially crafted repository, could possibly execute arbitrary code with the privileges of the process.
There are several alternative ways to fix this vulnerability. Please refer to Subversion Team Announce for more details.
