CVE-2026-7179
Received Received - Intake
Path Traversal in OSPG Binwalk WinCE Extraction Plugin

Publication date: 2026-04-27

Last updated on: 2026-04-29

Assigner: VulDB

Description
A security vulnerability has been detected in OSPG binwalk up to 2.4.3. This vulnerability affects the function read_null_terminated_string of the file src/binwalk/plugins/winceextract.py of the component WinCE Extraction Plugin. Such manipulation of the argument self.file_name leads to path traversal. The attack can only be performed from a local environment. The exploit has been disclosed publicly and may be used. The project maintainer confirms this issue: "I accept the existence of the Path Traversal vulnerability. However, as stated in the Github link, it reached EOL and as a result no actions should be expected." The GitHub repository mentions, that "[u]sers and contributors should migrate to binwalk v3." This vulnerability only affects products that are no longer supported by the maintainer.

Executive Summary

This vulnerability exists in the OSPG binwalk software up to version 2.4.3, specifically in the function read_null_terminated_string within the WinCE Extraction Plugin. It allows an attacker to manipulate the argument self.file_name to perform a path traversal attack. This means an attacker can potentially access files outside the intended directory by exploiting this flaw. However, the attack can only be performed from a local environment.

The vulnerability has been publicly disclosed and confirmed by the project maintainer, who also noted that the affected version has reached end-of-life and no fixes will be provided. Users are advised to migrate to binwalk version 3.

Impact Analysis

This vulnerability can allow a local attacker to perform path traversal, potentially accessing or manipulating files outside the intended scope of the application. This could lead to unauthorized access to sensitive files or data on the affected system.

Since the attack requires local access, remote exploitation is not possible. Additionally, the affected software version is no longer supported, meaning no patches will be provided, which could increase risk if the vulnerable version is still in use.

Detection Guidance

This vulnerability affects the function read_null_terminated_string in the WinCE Extraction Plugin of OSPG binwalk up to version 2.4.3 and involves path traversal via manipulation of the argument self.file_name. The attack can only be performed from a local environment.

Since the exploit requires local access and targets a specific function in binwalk versions up to 2.4.3, detection would involve verifying the presence of vulnerable binwalk versions on your system.

No specific detection commands or network-based detection methods are provided in the available information.

Mitigation Strategies

The project maintainer has confirmed the existence of the path traversal vulnerability but also stated that binwalk up to version 2.4.3 has reached end-of-life (EOL) and no further actions will be taken to fix this issue.

The recommended mitigation is to migrate to binwalk version 3, which is supported and presumably not affected by this vulnerability.

Since the attack requires local access, restricting local user permissions and access to vulnerable binwalk versions can also help reduce risk.
