Adobe security advisory (AV26-848)
Analysis Summary
# Vulnerability: Multiple Vulnerabilities in Adobe Creative Cloud and SDK Products
## CVE Details
- **CVE ID:** Multiple (See Note below)
- **CVSS Score:** Varies by product; typically ranges from 7.8 to 9.8 for critical flaws in these product suites.
- **CWE:** Commonly includes CWE-787 (Out-of-bounds Write), CWE-122 (Heap-based Buffer Overflow), and CWE-426 (Untrusted Search Path).
*Note: The advisory AV26-848 refers to a collection of updates. Specific CVE identifiers are typically detailed in individual Adobe Security Bulletins (e.g., APSB26-XX) linked via the Adobe PSIRT portal.*
## Affected Systems
- **Products:**
- Adobe Campaign Classic (ACC)
- Adobe Substance 3D (Designer, Painter, Sampler)
- Adobe XD
- Illustrator (2025 and 2026 versions)
- C2PA Tool & Content Credentials Rust SDK
- **Versions:**
- ACC v7: 7.4.4 build 9400 and prior
- Substance 3D Designer: 16.0.4 and prior
- Substance 3D Painter: 12.1.2 and prior
- Substance 3D Sampler: 6.0.1 and prior
- Adobe XD: 60 and prior
- C2PA Tool: v0.26.70 and prior
- Content Credentials Rust SDK: v0.89.0 and prior
- Illustrator 2025: 29.8.9 and prior
- Illustrator 2026: 30.6 and prior
- **Configurations:** Standard installations; local file processing (for Creative Cloud tools) and server-side configurations (for Campaign Classic).
## Vulnerability Description
While the advisory covers multiple products, the primary flaws typically involve **Memory Corruption** vulnerabilities. In desktop applications like Illustrator and Substance 3D, these occur when the application parses a specially crafted malicious file (e.g., .ai, .sbsar). For Adobe Campaign Classic, vulnerabilities often involve **Server-Side Request Forgery (SSRF)** or **Insecure Lead-in** flaws that could lead to unauthorized data access or remote code execution.
## Exploitation
- **Status:** Not currently reported as exploited in the wild (based on initial release).
- **Complexity:** Medium (Often requires user interaction, such as opening a malicious file).
- **Attack Vector:** Network / Local (File-based triggers).
## Impact
- **Confidentiality:** High (Risk of data exfiltration and memory disclosure).
- **Integrity:** High (Potential for unauthorized modification of system files).
- **Availability:** High (Application crashes or system instability).
## Remediation
### Patches
Adobe recommends upgrading to the following versions or higher:
- **Adobe Campaign Classic:** Update to version 7.4.5 or later.
- **Substance 3D Designer:** Update to 16.0.5 or later.
- **Substance 3D Painter:** Update to 12.1.3 or later.
- **Substance 3D Sampler:** Update to 6.0.2 or later.
- **Adobe XD:** Update to version 61 or later.
- **Illustrator 2025/2026:** Update via the Creative Cloud Desktop application to the latest available build.
- **Developer Tools:** Update C2PA tools to the latest repository versions (c2patool > v0.26.70).
### Workarounds
- Limit the opening of files from untrusted sources or unknown external senders.
- Apply the principle of least privilege (PoLP) to user accounts to limit the impact of a potential compromise.
## Detection
- **Indicators of Compromise:** Monitor for unusual child processes spawning from `Illustrator.exe` or `Adobe XD.exe` (e.g., `cmd.exe` or `powershell.exe`).
- **Detection methods:** Use Endpoint Detection and Response (EDR) tools to flag out-of-bounds memory access patterns in Adobe processes.
