CVE-2022-37866
In order to exploit this vulnerability an attacker needs collaboration by the remote repository as Ivy will issue http requests containing ".." sequences and a "normal" repository will not interpret them as part of the artifact coordinates.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.65%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
When Apache Ivy downloads artifacts from a repository it stores them in the local file system based on a user-supplied "pattern" that may include placeholders for artifacts coordinates like the organisation, module or version. If said coordinates contain "../" sequences - which are valid characters for Ivy coordinates in general - it is possible the artifacts are stored outside of Ivy's local cache or repository or can overwrite different artifacts inside of the local cache. In order to exploit this vulnerability an attacker needs collaboration by the remote repository as Ivy will issue http requests containing ".." sequences and a "normal" repository will not interpret them as part of the artifact coordinates. Users of Apache Ivy 2.0.0 to 2.5.1 should upgrade to Ivy 2.5.1.
