CVE-2008-2992 is a high-severity vulnerability affecting Adobe Acrobat and Reader versions 8.1.2 and earlier. This vulnerability allows remote attackers to execute arbitrary code through a specially crafted PDF file that invokes the util.printf JavaScript function with a malicious format string. Given the potential for arbitrary code execution, this vulnerability poses a significant risk to organizations using affected versions of the software.
With a CVSS score of 7.8, the vulnerability is classified as high severity. The exploitability of this vulnerability is critical, as it can be triggered without requiring any user privileges. Organizations must recognize the urgency of this threat and prioritize immediate patching to prevent potential exploitation.
The risk to organizations includes not only unauthorized access to sensitive data but also the potential for a widespread impact if the vulnerability is exploited, making it essential to assess the deployment environment for vulnerable versions.
Organizations should prioritize patching immediately to mitigate this vulnerability. As it is actively tracked in the CISA Known Exploited Vulnerabilities Catalog, the urgency for remediation cannot be overstated.
Vulnerability Details
The official description of CVE-2008-2992 states that it is a stack-based buffer overflow in Adobe Acrobat and Reader 8.1.2 and earlier versions. This vulnerability arises when a crafted PDF file calls the util.printf JavaScript function with a malicious format string argument, which is related to CVE-2008-1104. The vulnerability has a CVSS 3.1 score of 7.8, indicating high severity, and can lead to high confidentiality, integrity, and availability impacts.
Affected products include Adobe Acrobat and Adobe Reader, specifically versions up to and including 8.1.2. The vulnerability was published on November 4, 2008, and has been analyzed thoroughly, providing organizations with sufficient time to implement necessary security measures.
Technical Analysis
The root cause of CVE-2008-2992 is a stack-based buffer overflow that occurs in Adobe Acrobat and Reader when processing JavaScript code within a PDF file. This vulnerability can be exploited through a crafted PDF document that leverages the util.printf function, which requires user interaction to trigger.
The attack vector is local, meaning that the exploitation requires the execution of the malicious PDF file by the user. However, the attack complexity is low, as the attacker needs only to entice the user into opening the crafted document. No privileges are required, and user interaction is necessary for the attack to succeed.
The vulnerability has significant impacts on confidentiality, integrity, and availability. If exploited, it could lead to unauthorized access to sensitive information, data corruption, or service disruption. The CWE classification for this vulnerability is CWE-787, indicating a stack-based buffer overflow.
Risk & Impact Analysis
The real-world risk associated with CVE-2008-2992 is substantial. Organizations that deploy vulnerable versions of Adobe Acrobat and Reader are at risk of remote code execution attacks that could allow attackers to gain unauthorized access to systems and sensitive data.
The blast radius for this vulnerability is significant, particularly for organizations that utilize these applications for handling sensitive documents. An attacker could exploit the vulnerability to execute arbitrary code, potentially leading to further compromise of the organization's network.
Given the CVSS score of 7.8 and its inclusion in the CISA Known Exploited Vulnerabilities catalog, organizations should assess their exposure and prioritize remediation efforts accordingly. The urgency for patching is critical to mitigate the risk of exploitation.
