Technical details
The vulnerability exists in the target-side object rename handler of AIStore for Linux, which fails to properly validate the rename destination parameter. An unauthenticated remote attacker can bypass pathname restrictions by submitting a crafted rename request directly to an AIStore target, leading to arbitrary file creation or overwrite. Successful exploitation could enable code execution, privilege escalation, information disclosure, data tampering, or denial of service.
