CVE-2011-0611 is a high-severity vulnerability affecting multiple Adobe products, including Adobe Flash Player, Adobe AIR, and Adobe Reader. This vulnerability allows remote attackers to execute arbitrary code or cause a denial of service through crafted Flash content. The severity of this vulnerability is underscored by its CVSS score of 8.8, indicating a substantial risk to organizations that continue to use affected versions of the software.
The exploitation of this vulnerability has been observed in the wild since April 2011, as attackers utilized crafted Microsoft Office documents with embedded .swf files to trigger this vulnerability. Given the nature of the attacks, organizations should treat this vulnerability with urgency.
Adobe has indicated that the impacted products are end-of-life. Thus, organizations still using these products should disconnect them immediately to avoid potential exploitation. Failure to address this vulnerability can lead to significant security incidents.
Organizations should prioritize patching immediately and consider alternative solutions to mitigate the risks associated with using obsolete software.
Vulnerability Details
According to the official description, this vulnerability affects Adobe Flash Player versions before 10.2.154.27 on various platforms, including Windows, Mac OS X, Linux, and Solaris, as well as Android versions before 10.2.156.12. Additionally, Adobe AIR before 2.6.19140 and Authplay.dll in Adobe Reader versions prior to 9.4.4 and 10.x through 10.0.1 are vulnerable.
The vulnerability is categorized under CWE-843, indicating issues related to object type confusion. The CVSS score of 8.8 (High severity) reflects the vulnerability's potential impact, which includes high confidentiality, integrity, and availability impacts.
This vulnerability's published date was April 13, 2011, and it continues to pose risks to organizations that have not remediated it.
Technical Analysis
The root cause of CVE-2011-0611 stems from improper handling of Flash content, which may lead to arbitrary code execution. The attack vector is primarily network-based, allowing attackers to exploit this vulnerability through crafted Flash content embedded in documents.
The attack complexity is low, and attackers do not require any privileges to execute the exploit. However, user interaction is required, as the victim must open the malicious document for the exploitation to occur.
The impact of this vulnerability is significant, with high confidentiality, integrity, and availability impacts. Organizations must remain vigilant in monitoring for signs of exploitation.
Risk & Impact Analysis
The real-world risk from CVE-2011-0611 is substantial, given the critical nature of remote code execution vulnerabilities. Attackers may leverage this vulnerability to gain unauthorized access to systems, leading to data breaches or service disruptions.
The potential blast radius includes any organization still using vulnerable versions of Adobe products, especially among sectors that rely heavily on document sharing. The urgency assessment, based on the CVSS score and confirmed exploitation, indicates that organizations should address this vulnerability in priority patch cycles.
