How the CVE Works:
CVE-2025-27175 is an out-of-bounds write vulnerability in Adobe InDesign (versions ID20.1, ID19.5.2, and earlier). When a user opens a maliciously crafted file, the software fails to properly validate memory boundaries, allowing an attacker to write data beyond the allocated buffer. This corruption can lead to arbitrary code execution under the current user’s privileges. Exploitation requires user interaction, as the victim must open the malicious file. The flaw stems from improper bounds checking during file parsing, enabling attackers to manipulate memory structures and hijack execution flow.
DailyCVE Form:
Platform: Adobe InDesign
Version: ID20.1, ID19.5.2 (and earlier)
Vulnerability: Out-of-bounds write
Severity: Critical
Date: 04/28/2025
What Undercode Say:
Exploitation:
- Craft a malicious `.indd` file with payload targeting the buffer overflow.
2. Use heap grooming to control memory layout.
3. Overwrite critical pointers to redirect execution.
Proof of Concept (PoC) Snippet:
with open("exploit.indd", "wb") as f:
f.write(b"\x41" 1024) Trigger overflow
f.write(struct.pack("<Q", 0xdeadbeef)) Overwrite return address
Protection:
1. Apply Adobe’s patch (ID20.2 or later).
2. Disable opening untrusted `.indd` files via Group Policy.
3. Enable DEP/ASLR to mitigate code execution.
Detection Commands:
Check vulnerable versions on macOS: mdls -name kMDItemVersion /Applications/Adobe\ InDesign/Contents/Info.plist Windows registry check: reg query "HKLM\SOFTWARE\Adobe\InDesign" /v Version
Mitigation Script (Windows):
Block .indd files via AppLocker:
New-AppLockerPolicy -RuleType Path -FileInformation @(".indd") -Deny -User Everyone
Memory Analysis (WinDbg):
!analyze -v !address -summary
