Ivanti · Avalanche
A path traversal flaw in the AgentTaskHandler class of Ivanti Avalanche (6.3.3.101) lets a remote attacker read arbitrary files because a user-supplied path is not validated before file operations. An attacker needs network access and low-privileged credentials, though the authentication mechanism can be bypassed, and can use the flaw to disclose stored session cookies, which may enable further compromise.
This vulnerability allows remote attackers to read arbitrary files on affected installations of Ivanti Avalanche 6.3.3.101. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the AgentTaskHandler class. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to disclose stored session cookies, leading to further compromise. Was ZDI-CAN-15967.
