A hardcoded credential vulnerability exists in the firmware of multiple TP-Link routers (TL-WR845N v4, TL-WR850N v3, TL-WR902AC v4, Archer C20 v6 & Archer MR200 v5).  Authentication-related credential material is embedded within a password file in the firmware image and may be recovered through firmware analysis.

Successful exploitation could result in unauthorized access to privileged functions on affected devices.

Buffer Overflow
AV:A/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of TP-Link TL-WR902AC routers. Authentication is required to exploit this vulnerability. The specific flaw exists within the libcmm.so module. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root.

AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N

This vulnerability allows network-adjacent attackers to disclose sensitive information on affected installations of TP-Link TL-WR902AC routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the httpd service, which listens on TCP port 80 by default. The issue results from improper authentication. An attacker can leverage this vulnerability to disclose stored credentials, leading to further compromise.

OS Command Injection, Command Injection
CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Multiple TP-LINK products allow a network-adjacent unauthenticated attacker to execute arbitrary OS commands. Affected products/versions are as follows: TL-WR802N firmware versions prior to 'TL-WR802N(JP)V4221008', TL-WR841N firmware versions prior to 'TL-WR841N(JP)V14230506', and TL-WR902AC firmware versions prior to 'TL-WR902AC(JP)V3230506'.
