How the Mentioned CVE Works:
CVE-2025-21160 is an Integer Underflow vulnerability affecting Adobe Illustrator versions 29.1, 28.7.3, and earlier. This vulnerability occurs when an arithmetic operation results in a value smaller than the minimum limit of the integer type, causing it to wrap around to a large value. In this case, the flaw exists in the way Illustrator processes certain malicious files. When a user opens a specially crafted file, the integer underflow can be exploited to corrupt memory, leading to arbitrary code execution in the context of the current user. Successful exploitation requires user interaction, as the victim must open the malicious file. This vulnerability is critical due to its potential for remote code execution, which could allow an attacker to take full control of the affected system.

What Undercode Say:
Exploitation:
1. Exploit Code:
Crafting a malicious Illustrator file to trigger the integer underflow.
Example:
Pseudo-code for malicious file creation
with open("exploit.ai", "wb") as f:
f.write(b"\x41" 1000 + b"\xFF\xFF\xFF\xFF") Trigger underflow
2. Exploit Command:
Use a crafted file to exploit the vulnerability:
./illustrator exploit.ai
3. Exploit URL:
Host malicious files on a web server:
python3 -m http.server 8080
Protection:
1. Patch:
Apply the latest Adobe Illustrator update.
Download: Adobe Security Bulletin
2. Mitigation:
- Avoid opening untrusted files.
- Use sandboxing tools to isolate Illustrator.
3. Detection:
Scan for malicious files using antivirus tools:
clamscan exploit.ai
4. Monitoring:
Monitor system logs for unusual activity:
tail -f /var/log/syslog
5. Tools:
- Use memory analysis tools like Valgrind to detect underflows:
valgrind --tool=memcheck ./illustrator exploit.ai
- Employ fuzzing tools to identify vulnerabilities:
afl-fuzz -i input_dir -o output_dir ./illustrator
6. References:
By following these steps, users can both exploit and protect against CVE-2025-21160 effectively.
