CVE-2023-50224
TP-Link TL-WR841N dropbearpwd Improper Authentication Information Disclosure Vulnerability. This vulnerability allows network-adjacent attackers to disclose sensitive information on affected installations of TP-Link TL-WR841N 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. . Was ZDI-CAN-19899.
CVE-2023-39471
TP-Link TL-WR841N ated_tp Command Injection Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of TP-Link TL-WR841N routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the ated_tp service. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-21825.
CVE-2023-36489
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)_V4_221008', TL-WR841N firmware versions prior to 'TL-WR841N(JP)_V14_230506', and TL-WR902AC firmware versions prior to 'TL-WR902AC(JP)_V3_230506'.
CVE-2023-39745
TP-Link TL-WR940N V2, TP-Link TL-WR941ND V5 and TP-Link TL-WR841N V8 were discovered to contain a buffer overflow via the component /userRpm/AccessCtrlAccessRulesRpm. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted GET request.
CVE-2023-36354
TP-Link TL-WR940N V4, TL-WR841N V8/V10, TL-WR740N V1/V2, TL-WR940N V2/V3, and TL-WR941ND V5/V6 were discovered to contain a buffer overflow in the component /userRpm/AccessCtrlTimeSchedRpm. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted GET request.
CVE-2022-42433
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of TP-Link TL-WR841N TL-WR841N(US)_V14_220121 routers. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the ated_tp service. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-17356.
CVE-2022-0162
The vulnerability exists in TP-Link TL-WR841N V11 3.16.9 Build 160325 Rel.62500n wireless router due to transmission of authentication information in cleartextbase64 format. Successful exploitation of this vulnerability could allow a remote attacker to intercept credentials and subsequently perform administrative operations on the affected device through web-based management interface.
CVE-2019-17147
This vulnerability allows remote attackers to execute arbitrary code on affected installations of TP-LINK TL-WR841N routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the web service, which listens on TCP port 80 by default. When parsing the Host request header, the process does not properly validate the length of user-supplied data prior to copying it to a fixed-length static buffer. An attacker can leverage this vulnerability to execute code in the context of the admin user. Was ZDI-CAN-8457.
