Official Description
A vulnerability was found in Tenda CH22 1.0.0.1. This affects the function formSafeEmailFilter of the file /goform/SafeEmailFilter. Performing a manipulation of the argument page results in memory corruption. The attack is possible to be carried out remotely. The exploit has been made public and could be used.
Risk Analysis
This critical memory corruption vulnerability in Tenda CH22 firmware version 1.0.0.1 allows an unauthenticated, remote attacker to cause a denial of service or potentially execute arbitrary code by manipulating the 'page' argument in the '/goform/SafeEmailFilter' function. With a CVSS score of 9.8, this flaw poses a severe risk to system availability and integrity.
No public exploit is currently known for this vulnerability, but it is remotely exploitable with low attack complexity, making it a significant concern if an exploit emerges.
Users of Tenda CH22 firmware version 1.0.0.1 should apply any available patches or upgrades from the vendor. Ensure all network-facing devices are properly segmented and restrict access to management interfaces.
Technical Analysis
CVE-2025-11423 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
