Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

Directly requires timely identification, reporting, and correction of known software flaws like the integer underflow vulnerability in Adobe Illustrator on iPad, preventing exploitation through patching as advised in APSB25-04.

detect

Mandates vulnerability monitoring and scanning to identify systems running vulnerable versions of Adobe Illustrator affected by CVE-2025-21134.

prevent

Implements memory protections such as ASLR and DEP to mitigate arbitrary code execution resulting from the integer underflow when a malicious file is opened.

MITRE ATT&CK Enterprise TechniquesAI

T1204.002 Malicious File Execution
An adversary may rely upon a user opening a malicious file in order to gain execution.
Why these techniques?

Integer underflow in Adobe Illustrator enables arbitrary code execution upon opening a crafted malicious file, directly facilitating T1204.002 User Execution via Malicious File.

Deeper analysisAI

CVE-2025-21134 is an Integer Underflow (Wrap or Wraparound) vulnerability, classified as CWE-191, affecting Adobe Illustrator on iPad versions 3.0.7 and earlier. The flaw resides in the application and could result in arbitrary code execution in the context of the current user.

Exploitation requires local access with low complexity and no privileges, but user interaction is necessary as a victim must open a malicious file. An attacker can craft such a file to trick the user into opening it, achieving high impacts on confidentiality, integrity, and availability, as reflected in the CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).

Adobe Security Bulletin APSB25-04 provides details on mitigation, available at https://helpx.adobe.com/security/products/illustrator-mobile-ios/apsb25-04.html. The bulletin was published on 2025-01-14.
