Study Notes
Code Auditing Challenges
- Audits require expert-level manual or semi-manual code reviews, which are often tedious and prone to errors.
- Only 36% of companies find their auditing processes effective for enhancing code quality; 42% lack necessary personnel.
- High costs and broad attack surfaces prevent comprehensive auditing of deployed software.
- Manual audit slowness causes critical vulnerabilities to persist in updated applications.
Recent Vulnerabilities
- The xz supply chain attack exploited vulnerabilities in xz Utils’ complex binary code, previously overlooked due to the burden on open source auditors.
- This incident exemplifies the urgency for efficient tools to identify vulnerabilities in extensive software systems.
Programming Language Risks
- Low-level languages like C/C++ are prevalent in COTS software development but expose programmers to unsafe operations.
- Modern development environments mitigate risks by integrating abstractions and automatically generated checks.
Auditing Objectives
- The goal is to provide human auditors with a prioritized list of potentially exploitable code points in C programs, focusing on genuine security risks.
- This approach reduces false positives by omitting non-security-related code errors.
Hybrid Analysis
- Hybrid source-binary analysis can uncover vulnerabilities that neither source code nor binary analysis alone can detect.
- For instance, compiler optimization may eliminate protective code, creating vulnerabilities which can be identified through combined analysis.
Vulnerability Detection Algorithms
- Algorithms target insecure library calls in binaries, focusing on value set analysis (VSA) to determine security-sensitive data locations.
- Buffer Overflow Induction Loop (BOIL) detection seeks unsafe data movement patterns in code to identify custom implementations of risky functionalities.
Ranking System Effectiveness
- RANSAQ outperforms previous methodologies like Leopard in accurately ranking potentially vulnerable functions.
- It achieves superior coverage of vulnerable functions in the top ranks, identifying over 75% in the top 20% for specific applications.
Practical Applications and Testing
- RANSAQ successfully identified numerous high-severity CVEs across multiple applications, achieving high recall in detecting point of interest (POI).
- During DARPA CTF challenges, RANSAQ consistently identified hidden vulnerabilities within the top ranks, demonstrating its effectiveness even in novice-led teams.
Summary of Findings
- A total of 83 CVEs were categorized in the top POIs identified by RANSAQ across various applications, showing its precision and reliability in threat detection.
- The methodology enables auditors to focus on the highest risk vulnerabilities effectively.
