CVE-2009-3953 is a high-severity vulnerability that affects Adobe Acrobat and Reader versions prior to 9.3 and 8.2, allowing remote attackers to execute arbitrary code. The vulnerability stems from an issue in the U3D implementation related to a CLODProgressiveMeshDeclaration array boundary issue, which enables attackers to exploit malformed U3D data in PDF documents. This vulnerability poses significant risks to organizations, as it can be triggered through network interactions requiring user interaction.
The CVSS score of 8.8 signifies a high-severity rating, indicating the potential for serious consequences if exploited. Attackers may leverage this vulnerability to gain unauthorized access to sensitive data, leading to confidentiality, integrity, and availability impacts. Organizations should prioritize patching immediately to mitigate the risk associated with CVE-2009-3953.
The vulnerability has been confirmed in multiple versions of Adobe Acrobat and Reader across various operating systems, including Windows and Mac OS X. The threat posed by this vulnerability is further emphasized by its inclusion in the Known Exploited Vulnerabilities (KEV) catalog, indicating its relevance in the current threat landscape.
Organizations using affected versions of Adobe Acrobat and Reader must take immediate action to apply the necessary updates per vendor instructions to prevent potential exploitation.
Vulnerability Details
The U3D implementation in Adobe Reader and Acrobat 9.x before 9.3, 8.x before 8.2 on Windows and Mac OS X, and 7.x before 7.1.4 allows remote attackers to execute arbitrary code via malformed U3D data in a PDF document, related to a CLODProgressiveMeshDeclaration array boundary issue.
The CVSS score for this vulnerability is 8.8, classified as high severity. It has a base score defined by a high impact on confidentiality, integrity, and availability. It requires no privileges and involves user interaction to exploit, making it a significant risk for organizations.
Technical Analysis
The root cause of CVE-2009-3953 lies in the improper handling of U3D data within Adobe's software, leading to an array boundary issue. Attackers can exploit this vulnerability through network vectors, with low complexity and no authentication required. However, user interaction is necessary to trigger the exploit, as the malicious PDF must be opened by the user.
This vulnerability can lead to significant impacts across confidentiality, integrity, and availability, as successful exploitation may allow attackers to execute arbitrary code on the victim's system. Organizations should be vigilant in monitoring for any signs of exploitation and ensure that all users are aware of the risks associated with opening untrusted PDF documents.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to sensitive information and potential system compromise. The vulnerability's high CVSS score indicates that it poses a significant risk if left unaddressed. The urgency for remediation is critical, given its active status in the KEV catalog and the potential for exploitation.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | Yes |
Public PoC | Yes |
Actively Exploited | Yes |
Ransomware Use | No |
Affected Versions
The vulnerability affects Adobe Acrobat versions prior to 9.3, 8.x prior to 8.2, and 7.x prior to 7.1.4. Additionally, it impacts various versions of OpenSUSE and SUSE Linux Enterprise products.
