CERT-In warns of critical Adobe vulnerabilities in InDesign, Illustrator, and more. Update now to prevent code execution, privilege escalation, and crashes.

Overview

The Indian Computer Emergency Response Team (CERT-In) has issued a critical security advisory (CIVN-2025-0025) detailing multiple vulnerabilities across various Adobe products. These security flaws pose significant risks, including unauthorized code execution, privilege escalation, security bypass, and denial-of-service (DoS) attacks. Users and administrators of affected Adobe software are urged to apply security updates immediately to mitigate these risks.

Affected Software

The vulnerabilities impact multiple Adobe products across different versions. The affected software includes:

• Adobe InDesign
  • InDesign 1D20.0 and earlier versions
  • InDesign 1D19.5.1 and earlier versions
• Adobe Commerce
  • Adobe Commerce 2.4.4-p11 and earlier versions
  • Adobe Commerce B2B 1.3.3-p11 and earlier versions
  • Magento Open Source 2.4.4-p11 and earlier versions
• Adobe Substance 3D Stager
  • Substance 3D Stager 3.1.0 and earlier versions
• Adobe InCopy
  • InCopy 20.0 and earlier versions
  • InCopy 19.5.1 and earlier versions
• Adobe Illustrator
  • Illustrator 2025 29.1 and earlier versions
  • Illustrator 2024 28.7.3 and earlier versions
• Adobe Substance 3D Designer
  • Substance 3D Designer 14.0.2 and earlier versions
• Adobe Photoshop Elements
  • Photoshop Elements 2025.0 (Builds: 20240918.PSE.cae27345, 20240918.PSE.d3263bae)

Risk and Impact Assessment

Risk Assessment

These vulnerabilities are classified as Critical, making them high-risk threats that can lead to unauthorized access to sensitive data, system instability, and potential compromise of critical operations.

Impact Assessment

• Arbitrary Code Execution: Attackers can exploit the vulnerabilities to run malicious code on affected systems, potentially gaining full control over compromised machines.
• Privilege Escalation: Unauthorized users may gain elevated privileges, allowing them to modify system settings and access restricted resources.
• Security Feature Bypass: Malicious actors can circumvent security controls, enabling further exploitation of the affected systems.
• Denial of Service (DoS): Successful exploitation can result in system crashes or unavailability, disrupting operations and productivity.

Technical Details

The vulnerabilities stem from multiple security flaws, including:

• Out-of-Bounds Write: Writing data outside the allocated buffer, leading to potential code execution.
• Integer Underflow (Wraparound): Arithmetic errors causing improper memory operations.
• Heap-Based Buffer Overflow: Exploitation can lead to memory corruption and code execution.
• Out-of-Bounds Read: Reading data beyond allocated memory, potentially exposing sensitive information.
• NULL Pointer Dereference: Application crashes or unpredictable behavior.
• Improper Input Validation: Malicious input bypassing security checks.
• Path Traversal: Unauthorized file system access.
• Incorrect Authorization & Improper Access Control: Attackers gaining higher privileges.
• Stored Cross-Site Scripting (XSS): Injection of malicious scripts into applications.
• Use After Free: Exploiting released memory pointers for arbitrary code execution.
• Time-of-Check to Time-of-Use (TOCTOU) Race Condition: Exploiting system state changes during execution.
• Stack-Based Buffer Overflow: Execution of attacker-controlled code.
• Temporary File Creation with Incorrect Permissions: Unauthorized access to sensitive files.

Mitigation and Recommended Actions

CERT-In strongly recommends applying security patches as soon as possible to prevent exploitation. Users and administrators should:

1. Update Software: Apply the latest security updates available on the Adobe Security Bulletin.
2. Monitor System Activity: Regularly check for unusual activities or unauthorized access.
3. Restrict Privileges: Minimize user privileges to reduce potential impact.
4. Enable Security Features: Use built-in security controls such as access controls and firewalls.
5. Regular Backups: Maintain updated backups to ensure data recovery in case of an attack.
6. Security Awareness: Educate users on recognizing phishing attempts and suspicious activities.

Conclusion

The vulnerabilities reported in Adobe products highlight the growing need for proactive security measures in software environments. System administrators and security teams must act swiftly to apply patches and implement best practices to safeguard their infrastructure. Organizations relying on Adobe products should remain vigilant, ensuring that security updates are promptly installed to prevent potential exploitation. Staying updated and following security advisories is crucial in mitigating threats and maintaining a secure digital ecosystem.
