VAR-200109-0013

Vulnerability from variot - Updated: 2025-04-03 20:42

Check Point FireWall-1 3.0b through 4.1 for Solaris allows local users to overwrite arbitrary files via a symlink attack on temporary policy files that end in a .cpp extension, which are set world-writable. Check Point Firewall-1 is a commercial firewall implementation designed for small to enterprise sized networks. A problem with Firewall-1 has been discovered that makes it possible for a local user to change the permissions of root-owned files to world-writable, and potentially gain elevated privileges. The problem is in the creation of predictable /tmp files. Upon editing firewall rules and committing them, a file is created in /tmp using the name of the policy as a filename, and .cpp as an extension. It's possible for a local user to create symbolic links to root-owned files, which will result in the files becoming world-writable, and potentially gain local root access. The file's attributes are set to rw-rw-rw- (666), which allows anyone to modify the file. Since the file is not checked whether it is a link file when the file is created, an attacker can create a file in any directory through a link attack. If an attacker has permission to compile firewall policies and has access to the system where the firewall resides, this vulnerability could be exploited to elevate privileges

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
