Learn about CVE-2022-38072, a CWE-118 vulnerability in ADMesh and libslic3r. Understand the impact, affected systems, and mitigation steps for this heap buffer overflow issue.
This article provides an overview of CVE-2022-38072, an improper array index validation vulnerability affecting ADMesh and libslic3r.
Understanding CVE-2022-38072
CVE-2022-38072 is an array index validation vulnerability found in the stl_fix_normal_directions functionality of ADMesh software. It can lead to a heap buffer overflow when processing specially-crafted STL files. The vulnerability affects specific versions of ADMesh and libslic3r.
What is CVE-2022-38072?
CVE-2022-38072 is a CWE-118: Incorrect Access of Indexable Resource ('Range Error') vulnerability that allows an attacker to trigger a heap buffer overflow by providing a malicious STL file to the affected software.
The Impact of CVE-2022-38072
This vulnerability may be exploited by an attacker to execute arbitrary code or crash the software, potentially leading to a denial of service condition. It poses a moderate risk as it requires the ability to provide a specially-crafted file to the target system.
Technical Details of CVE-2022-38072
Vulnerability Description
The vulnerability exists due to improper array index validation in ADMesh versions Master Commit 767a105 and v0.98.4, as well as libslic3r version Master Commit b1a5500. An attacker can exploit this issue by providing a crafted STL file, causing a heap buffer overflow.
Affected Systems and Versions
ADMesh versions impacted include Master Commit 767a105 and v0.98.4, while libslic3r version Master Commit b1a5500 is also affected.
Exploitation Mechanism
By supplying a specially-crafted STL file to the vulnerable software, an attacker can trigger the heap buffer overflow, potentially leading to arbitrary code execution or denial of service.
Mitigation and Prevention
Immediate Steps to Take
Users are advised to update ADMesh and libslic3r to non-vulnerable versions, if available. Additionally, exercise caution when processing STL files from untrusted sources.
Long-Term Security Practices
Implementing input validation mechanisms and secure coding practices can help prevent similar vulnerabilities in the future. Regular software updates and security assessments are crucial for maintaining a secure environment.
