CVE-2020-9563
📋 TL;DR
A heap overflow vulnerability in Adobe Bridge allows attackers to execute arbitrary code on affected systems. This affects users running Adobe Bridge version 10.0.1 or earlier. Successful exploitation requires user interaction, such as opening a malicious file.
💻 Affected Systems
- Adobe Bridge
📦 What is this software?
Bridge by Adobe
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attacker gaining full control of the affected machine, potentially leading to data theft, ransomware deployment, or lateral movement within the network.
Likely Case
Local privilege escalation or arbitrary code execution in the context of the current user, enabling data access, persistence mechanisms, or credential harvesting.
If Mitigated
Limited impact due to application sandboxing, user privilege restrictions, or network segmentation preventing lateral movement.
🎯 Exploit Status
Exploitation requires user interaction (opening malicious file). Heap overflow vulnerabilities typically require precise memory manipulation.
