CVE-2022-36060 is a high-severity vulnerability affecting the Matrix React SDK, a popular chat protocol SDK for React JavaScript. This vulnerability allows events sent with specific strings to disrupt or impede the functionality of the SDK, potentially causing room or event tile crashes. While the application may remain functional in other areas, certain rooms or events will not be rendered correctly. The issue has been addressed in version 3.53.0 of the matrix-react-sdk, and users are strongly advised to upgrade to this version as there are currently no known workarounds.
The vulnerability has a CVSS score of 8.2, categorizing it as high severity. The attack vector is network-based with low complexity, requiring no privileges or user interaction. The integrity impact is low, while the availability impact is high, underlining the critical nature of this issue. Organizations should prioritize patching immediately to prevent disruptions in service.
Given that this vulnerability has been classified as high severity, organizations using the Matrix React SDK need to be vigilant. The potential for crashes in specific rooms or events could lead to significant disruptions in communication. Therefore, the urgency of applying the patch cannot be overstated.
Currently, there are no known exploits for this vulnerability, and it has not been included in the Known Exploited Vulnerabilities (KEV) catalog. However, the absence of known exploits does not diminish the importance of remediation.
Organizations should take the necessary steps to upgrade their version of the matrix-react-sdk to 3.53.0 immediately to bolster their defense against potential exploitation.
Vulnerability Details
The official description of CVE-2022-36060 indicates that it occurs in the matrix-react-sdk, specifically when special strings are sent in key places. This can cause disruptions, leading to crashes in certain rooms or events while the rest of the application may still appear functional. The vulnerability has been classified under CWE-1321.
The CVSS score from the primary source indicates a base score of 5.3, representing medium severity, while a secondary source lists a higher base score of 8.2, indicating high severity. This discrepancy highlights the need for organizations to assess their specific context and the potential impact of this vulnerability.
Affected versions of the matrix-react-sdk are all versions prior to 3.53.0. The vulnerability has been published on March 28, 2023, and modified on November 21, 2024.
Technical Analysis
The root cause of CVE-2022-36060 lies in how the matrix-react-sdk processes certain events. Specifically, when special strings are included in events, the SDK can fail to handle them correctly, leading to application crashes in specific rooms or event tiles.
The attack vector is classified as network-based, meaning that an attacker could exploit the vulnerability remotely without needing physical access to the system. The complexity of the attack is low, as there are no special privileges required, nor is user interaction needed for the attack to succeed.
In terms of impact, the vulnerability primarily affects availability, with a high impact score indicating that the crashes can significantly disrupt user experience. The integrity impact is rated low, suggesting that data integrity is not directly compromised by this vulnerability.
Risk & Impact Analysis
Organizations utilizing the matrix-react-sdk should evaluate their deployment configurations to identify potential exposure to this vulnerability. The application’s functionality may be impaired, leading to disruptions in communication, particularly in critical environments where reliable chat functionality is essential.
The potential for crashes in specific rooms or events can create a significant blast radius, especially in large organizations with numerous active rooms. The urgency for remediation is high given the overall impact on availability, emphasized by the CVSS score of 8.2, which indicates a serious risk to operational integrity.
Given the current absence of known exploits or active campaigns targeting this vulnerability, organizations should nonetheless prioritize patching to mitigate any future risks that may arise as attackers increasingly look for unpatched vulnerabilities to exploit.
