CVE-2022-1714
📋 TL;DR
CVE-2022-1714 is an out-of-bounds read vulnerability in radare2 reverse engineering framework versions prior to 5.7.0. This allows attackers to read sensitive information from adjacent memory locations, potentially exposing secrets or causing program crashes. Users of radare2 for binary analysis, security research, or reverse engineering are affected.
💻 Affected Systems
- radare2
📦 What is this software?
Radare2 by Radare
⚠️ Risk & Real-World Impact
Worst Case
Information disclosure of sensitive memory contents including passwords, encryption keys, or other application secrets, potentially leading to complete system compromise if combined with other vulnerabilities.
Likely Case
Program crash (denial of service) or limited information disclosure from adjacent memory buffers.
If Mitigated
Minimal impact if proper memory protections (ASLR, DEP) are enabled and the application runs with limited privileges.
🎯 Exploit Status
Exploitation requires the attacker to provide malicious input to radare2, which could be embedded in analyzed binaries or scripts. The vulnerability is publicly documented with proof-of-concept details available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 5.7.0 and later
Vendor Advisory: https://github.com/radareorg/radare2/commit/3ecdbf8e21186a9c5a4d3cfa3b1e9fd27045340e
Restart Required: No
Instructions:
1. Update radare2 to version 5.7.0 or later using your package manager. 2. For source installations: git clone https://github.com/radareorg/radare2 && cd radare2 && sys/install.sh. 3. Verify installation with 'r2 -v' to confirm version 5.7.0+.
🔧 Temporary Workarounds
Restrict radare2 usage
linuxLimit radare2 execution to trusted users and environments only
chmod 750 /usr/bin/radare2
setfacl -m u:trusteduser:rx /usr/bin/radare2
Run with reduced privileges
allExecute radare2 with minimal permissions using privilege separation
sudo -u nobody radare2 [file]
runas /user:lowprivuser radare2.exe [file]
🧯 If You Can't Patch
- Isolate radare2 to dedicated analysis systems with no sensitive data or network access
- Implement application whitelisting to prevent execution of untrusted binaries with radare2
🔍 How to Verify
Check if Vulnerable:
Run 'r2 -v' and check if version is below 5.7.0. If command returns 'radare2 5.6.0' or similar lower version, system is vulnerable.
Check Version:
r2 -v | grep -o 'radare2 [0-9.]\+'
Verify Fix Applied:
Execute 'r2 -v' and confirm output shows version 5.7.0 or higher. Test with known problematic inputs from vulnerability reports.
📡 Detection & Monitoring
Log Indicators:
- Segmentation fault or access violation errors in system logs when radare2 crashes
- Unusual memory access patterns from radare2 process
Network Indicators:
- Typically none as this is a local vulnerability
SIEM Query:
process.name:"radare2" AND (event.action:"segmentation_fault" OR event.action:"access_violation")
