CVE-2010-3765 is a critical vulnerability affecting multiple Mozilla products, including Firefox, Thunderbird, and SeaMonkey. This vulnerability allows remote attackers to execute arbitrary code due to memory corruption triggered by specific JavaScript operations. The affected versions of Firefox range from 3.5.x through 3.5.14 and 3.6.x through 3.6.11, while Thunderbird versions 3.1.6 and earlier, as well as SeaMonkey versions before 2.0.10, are also impacted. The severity of this vulnerability is underscored by its exploitation in the wild, notably during October 2010 by the Belmoo malware.
The vulnerability has been assigned a CVSS score of 9.8, categorizing it as critical. This rating indicates a high level of risk for organizations using the affected software. Given the potential for remote code execution, it is crucial for organizations to take immediate action to protect their systems.
Organizations should prioritize patching immediately to mitigate risks associated with CVE-2010-3765. The exploitation status indicates that this vulnerability is included in the Known Exploited Vulnerabilities (KEV) catalog, highlighting its relevance and urgency in the current threat landscape.
Given the critical nature of this vulnerability, organizations must assess their exposure and take the necessary steps to update their software to the latest secure versions. Failure to do so could result in severe consequences, including unauthorized access and data breaches.
Vulnerability Details
The official description of CVE-2010-3765 indicates that when JavaScript is enabled in the affected products, attackers can exploit vulnerabilities related to the nsCSSFrameConstructor::ContentAppended function, the appendChild method, incorrect index tracking, and the creation of multiple frames. This exploitation leads to memory corruption, resulting in the ability to execute arbitrary code.
With a CVSS version 3.1 score of 9.8, the risk associated with this vulnerability is extremely high. The attack vector is network-based, with low complexity and no privileges required for exploitation. No user interaction is necessary, amplifying the risk for organizations.
Technical Analysis
The root cause of CVE-2010-3765 lies in a flaw within the JavaScript handling of the affected Mozilla products. Specifically, the issues pertain to how the appendChild method interacts with the memory allocation for frames. When this function is improperly executed, it can lead to memory corruption, allowing for arbitrary code execution.
The attack vector is through the network, making it accessible to remote attackers. The complexity of the attack is low, and it does not require any user privileges or interaction, making exploitation easier for attackers. The impacts on confidentiality, integrity, and availability are all classified as high, indicating a severe threat to affected organizations.
Risk & Impact Analysis
Organizations utilizing affected versions of Mozilla products face substantial risks due to CVE-2010-3765. The potential for remote code execution can lead to unauthorized access, data breaches, and significant operational disruptions. Given the widespread usage of Firefox, Thunderbird, and SeaMonkey, the attack surface is extensive, enhancing the urgency for remediation.
Furthermore, the inclusion of this vulnerability in the KEV catalog indicates that it is actively being exploited, underscoring the need for organizations to implement immediate protective measures. The CVSS score of 9.8 classifies this vulnerability as critical, emphasizing the potential consequences of inaction.
