How CVE-2025-27204 Works
This vulnerability in Adobe After Effects (versions 25.1, 24.6.4 and earlier) stems from improper memory handling when parsing malicious project files. An out-of-bounds read occurs when the software accesses memory beyond the allocated buffer while processing crafted AE project data. This allows attackers to leak ASLR offsets or other sensitive data, aiding further exploitation. User interaction is required—opening a malicious .aep file triggers the flaw. Successful exploitation could lead to information disclosure or serve as a stepping stone for RCE chains.
DailyCVE Form
Platform: Adobe After Effects
Version: ≤25.1, ≤24.6.4
Vulnerability: OOB Read
Severity: Critical
Date: 04/15/2025
What Undercode Say:
Exploitation:
- Crafted .aep file triggers OOB read during project load.
- Memory leaks reveal ASLR offsets or sensitive data.
3. Combine with other flaws for RCE.
PoC (Conceptual):
import struct
malicious_aep = b"\x41" 1024 + struct.pack("<I", 0xdeadbeef) Truncated for brevity
with open("exploit.aep", "wb") as f:
f.write(malicious_aep)
Detection:
Check installed version (macOS): mdls -name kMDItemVersion /Applications/Adobe\ After\ Effects/Contents/Info.plist Windows (PowerShell): Get-ItemProperty "HKLM:\SOFTWARE\Adobe\After Effects\" | Select-Object Version
Mitigation:
1. Update to After Effects ≥25.2.
2. Restrict .aep files from untrusted sources.
3. Apply MEMORY_SAFE_HEAP flags if compiling custom plugins.
Memory Analysis (WinDbg):
!address /f:Heap -c:"!heap -p -a @$t0" s -b 0 L?80000000 41 41 41 41 Scan for attacker-controlled buffers
Network Indicators:
– Monitor SMB/HTTP transfers of .aep files with abnormal headers.
YARA Rule:
rule AE_OOB_Read {
strings:
$magic = { 41 45 50 72 } // "AEPR" malformed
condition:
$magic at 0 and filesize < 10MB
}
Patch Verification:
Linux/macOS (sha256sum): shasum -a 256 "/Applications/Adobe After Effects/Contents/Info.plist"
