Cross-Site Request Forgery (CSRF)
CVE-2024-30252
Summary
Livemarks is a browser extension that provides RSS feed bookmark folders. Versions of Livemarks prior to 3.7 are vulnerable to cross-site request forgery. A malicious website may be able to coerce the extension to send an authenticated GET request to an arbitrary URL. An authenticated request is a request where the cookies of the browser are sent along with the request. The `subscribe.js` script uses the first parameter from the current URL location as the URL of the RSS feed to subscribe to and checks that the RSS feed is valid XML. `subscribe.js` is accessible by an attacker website due to its use in `subscribe.html`, an HTML page that is declared as a `web_accessible_resource` in `manifest.json`. This issue may lead to `Privilege Escalation`. A CSRF breaks the integrity of servers running on a private network. A user of the browser extension may have a private server with dangerous functionality, which is assumed to be safe due to network segmentation. Upon receiving an authenticated request instantiated from an attacker, this integrity is broken. Version 3.7 fixes this issue by removing subscribe.html from `web_accessible_resources`.

CWE-352 - Cross-Site Request Forgery (CSRF)
Cross-Site Request Forgery (CSRF) is a vulnerability that allows an attacker to make arbitrary requests in an authenticated vulnerable web application and disrupt the integrity of the victim’s session. The impact of a successful CSRF attack may range from minor to severe, depending upon the capabilities exposed by the vulnerable application and privileges of the user. An attacker may force the user to perform state-changing requests like transferring funds, changing their email address or password etc. However, if an administrative level account is affected, it may compromise the whole web application and associated sensitive data.
