How the CVE Works:
CVE-2025-24453 exploits a heap-based buffer overflow vulnerability in Adobe InDesign (versions ID20.1, ID19.5.2, and earlier). When a user opens a maliciously crafted `.indd` file, the application fails to properly validate memory boundaries during file parsing. This allows an attacker to overwrite adjacent heap memory, leading to arbitrary code execution under the current user’s privileges. The flaw stems from improper bounds checking when processing font or image data embedded in the file.
DailyCVE Form:
Platform: Adobe InDesign
Version: ID20.1, ID19.5.2 (earlier)
Vulnerability: Heap Overflow
Severity: Critical
Date: 04/28/2025
What Undercode Say:
Exploitation:
- Craft a malicious `.indd` file with oversized font/image metadata.
2. Trigger overflow via nested style definitions.
3. Overwrite heap control structures for RCE.
Protection:
1. Patch to InDesign ID20.2 or later.
2. Disable opening untrusted `.indd` files.
Analytics:
- Attack Vector: Local (user interaction)
- Complexity: Low (exploitable via social engineering)
- Impact: Full system compromise
Commands:
- Check version (macOS):
mdls -name kMDItemVersion /Applications/Adobe\ InDesign/Contents/Info.plist
- Mitigation (Windows):
Set-ItemProperty -Path "HKLM:\SOFTWARE\Adobe\InDesign" -Name "DisableUntrustedFiles" -Value 1
PoC (Partial):
with open("exploit.indd", "wb") as f:
f.write(b"\x41" 5000) Overflow trigger
Detection (YARA):
rule indd_heap_overflow {
strings:
$sig = "FontOverflowTrigger"
condition:
$sig in (0..100KB)
}
