Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: A critical flaw in Mozilla products where `resource:` URLs are not properly restricted. ๐ **Consequences**: Attackers can bypass the Same Origin Policy (SOP).โฆ
๐ก๏ธ **Root Cause**: Improper access control and permission management. ๐ **Flaw**: The application fails to correctly restrict the usage of `resource:` URLs.โฆ
๐ป **Privileges**: Remote attackers gain the ability to bypass SOP. ๐ต๏ธ **Data Access**: They can access local `resource:` URLs, potentially reading local files or internal browser data.โฆ
๐ฅ **Public Exp?**: YES. ๐ **PoC**: Available on GitHub (e.g., `Firefox-35-37-Exploit`). ๐งฉ **Combo**: Often combined with CVE-2015-0802 for full exploitation. Wild exploitation is possible via malicious websites.
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: Scan for Firefox/Thunderbird versions older than the patched release. ๐ก **Detection**: Look for network traffic or logs involving suspicious `resource:` URL access patterns from web pages.โฆ
โ **Fixed**: YES. ๐ **Patches**: Official advisories released by Red Hat (RHSA-2015:0771), Debian (DSA-3212), and Ubuntu (USN-2550-1). ๐ **Action**: Update to the latest stable version of Firefox/Thunderbird immediately.
Q9What if no patch? (Workaround)
๐ง **No Patch Workaround**: 1. Disable JavaScript if possible (breaks usability). 2. Use strict content security policies. 3. Isolate browsing profiles. 4. **Best**: Upgrade immediately.โฆ
๐จ **Urgency**: HIGH. ๐ฅ **Priority**: Critical. Since it allows SOP bypass and has public exploits, it is actively dangerous. Organizations must patch Firefox/Thunderbird instances immediately to prevent remote attacks.
