**Name of the Vulnerable Software and Affected Versions** TP-Link TL-WR902AC (affected versions not specified) **Description** The issue is related to inadequate access control in the httpd service of TP-Link TL-WR902AC Wi-Fi routers. This allows a remote attacker to gain unauthorized access to protected information. The specific flaw exists within the httpd service, which listens on TCP port 80 by default, and results from improper authentication. An attacker can leverage this vulnerability to disclose stored credentials, leading to further compromise. No information is provided about the estimated number of potentially affected devices worldwide or real-world incidents where this issue was exploited. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** TP-Link TL-WR841N (affected versions not specified) **Description** An improper authentication issue exists in the `dropbearpwd` component of the firmware, specifically within the `httpd` service that listens on TCP port 80. This flaw allows network-adjacent attackers to bypass authentication and disclose sensitive information, such as stored credentials, via HTTP GET requests. In real-world incidents, the APT28 group exploited this issue in over 18,000 devices across 120 countries to hijack DNS settings and perform adversary-in-the-middle attacks, redirecting traffic through malicious servers to intercept credentials and conduct espionage. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability. Update firmware to the latest available version. Change the router administration password. Disable remote management access. Reboot the device to clear potential attacker implants.
