CVE-2022-34899 (GCVE-0-2022-34899)
Vulnerability from cvelistv5 – Published: 2022-07-18 14:17 – Updated: 2024-08-03 09:22
VLAI
Summary
This vulnerability allows local attackers to escalate privileges on affected installations of Parallels Access 6.5.4 (39316) Agent. An attacker must first obtain the ability to execute low-privileged code on the target host system in order to exploit this vulnerability. The specific flaw exists within the Parallels service. By creating a symbolic link, an attacker can abuse the service to execute a file. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of root. Was ZDI-CAN-16134.

Mitigation
Phase: Implementation
Description:
- The most basic advice for TOCTOU vulnerabilities is to not perform a check before the use. This does not resolve the underlying issue of the execution of a function on a resource whose state and identity cannot be assured, but it does help to limit the false sense of security given by the check.
Mitigation
Phase: Implementation
Description:
- When the file being altered is owned by the current user and group, set the effective gid and uid to that of the current user and group when executing this statement.
Mitigation
Phase: Architecture and Design
Description:
- Limit the interleaving of operations on files from multiple processes.
Mitigation
Phases: Implementation, Architecture and Design
Description:
- If you cannot perform operations atomically and you must share access to the resource between multiple processes or threads, then try to limit the amount of time (CPU cycles) between the check and use of the resource. This will not fix the problem, but it could make it more difficult for an attack to succeed.
Mitigation
Phase: Implementation
Description:
- Recheck the resource after the use call to verify that the action was taken appropriately.
Mitigation
Phase: Architecture and Design
Description:
- Ensure that some environmental locking mechanism can be used to protect resources effectively.
Mitigation
Phase: Implementation
Description:
- Ensure that locking occurs before the check, as opposed to afterwards, such that the resource, as checked, is the same as it is when in use.
CAPEC-27: Leveraging Race Conditions via Symbolic Links
This attack leverages the use of symbolic links (Symlinks) in order to write to sensitive files. An attacker can create a Symlink link to a target file not otherwise accessible to them. When the privileged program tries to create a temporary file with the same name as the Symlink link, it will actually write to the target file pointed to by the attackers' Symlink link. If the attacker can insert malicious content in the temporary file they will be writing to the sensitive file by using the Symlink. The race occurs because the system checks if the temporary file exists, then creates the file. The attacker would typically create the Symlink during the interval between the check and the creation of the temporary file.
CAPEC-29: Leveraging Time-of-Check and Time-of-Use (TOCTOU) Race Conditions
This attack targets a race condition occurring between the time of check (state) for a resource and the time of use of a resource. A typical example is file access. The adversary can leverage a file access race condition by "running the race", meaning that they would modify the resource between the first time the target program accesses the file and the time the target program uses the file. During that period of time, the adversary could replace or modify the file, causing the application to behave unexpectedly.
