CVE-2007-5659 is a high-severity vulnerability affecting Adobe Acrobat and Reader versions 8.1.1 and earlier. This vulnerability allows remote attackers to exploit multiple buffer overflows through specially crafted PDF files containing long arguments to unspecified JavaScript methods. The potential consequences of this flaw include arbitrary code execution, which could severely compromise the security of affected systems. Organizations utilizing these Adobe products must understand the critical nature of this vulnerability and take immediate remedial actions.
The CVSS score for this vulnerability is 7.8, categorizing it as high severity. This score reflects the significant risk posed to organizations, particularly given the potential for exploitation via remote methods. Attackers may leverage this vulnerability to execute arbitrary code, thereby gaining unauthorized access to sensitive information or disrupting system integrity.
Risk to organizations includes unauthorized access and potential data breaches, making it imperative for security teams to prioritize patching efforts. Organizations should address this vulnerability urgently, as exploitation could lead to severe consequences including data loss and operational downtime.
The exploitation status is critical, with known exploits available in the wild, and this vulnerability has been included in the Known Exploited Vulnerabilities (KEV) catalog. Organizations must take immediate action to remediate this vulnerability to mitigate risks associated with potential exploitation.
Vulnerability Details
This vulnerability allows multiple buffer overflows in Adobe Reader and Acrobat 8.1.1 and earlier, enabling remote attackers to execute arbitrary code via a PDF file with long arguments to unspecified JavaScript methods. The issue may be subsumed by CVE-2008-0655.
The CVSS 3.1 score of 7.8 indicates high severity, reflecting significant potential impact on confidentiality, integrity, and availability. The attack vector is local, and the attack complexity is low, requiring no privileges, but user interaction is necessary. Organizations must ensure all affected products are updated promptly.
Technical Analysis
The root cause of this vulnerability stems from improper handling of input in Adobe Reader and Acrobat, leading to buffer overflows. Attackers can exploit this flaw by crafting malicious PDF files with excessively long arguments directed at vulnerable JavaScript methods, thus executing arbitrary code when the file is opened.
The attack vector is local, meaning the attacker must convince a user to open the malicious PDF. The complexity is low, with no specific privileges required, but user interaction is necessary. The impacts on confidentiality, integrity, and availability are critical, leading to potential unauthorized access and disruptions.
Risk & Impact Analysis
Real-world deployment of this vulnerability poses significant risks to organizations. Attackers could exploit this flaw to gain unauthorized access, execute arbitrary code, and compromise sensitive data. The blast radius is extensive due to the widespread use of Adobe Acrobat and Reader, making it a prime target for attackers.
Organizations should assess the urgency based on the CVSS score and the presence in the KEV catalog. Given the high severity and potential exploitation, organizations must prioritize patching immediately to mitigate risks.
