CVSS: 7.8EPSS: 0%CPEs: 2EXPL: 2CVE-2020-10883 – TP-Link Archer A7 File System Incorrect Permission Assignment for Critical Resource Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2020-10883
This vulnerability allows local attackers to escalate privileges on affected installations of TP-Link Archer A7 Firmware Ver: 190726 AC1750 routers. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the file system. The issue lies in the lack of proper permissions set on the file system. An attacker can leverage this vulnerability to escalate privileges. • https://www.exploit-db.com/exploits/48331 http://packetstormsecurity.com/files/157255/TP-Link-Archer-A7-C7-Unauthenticated-LAN-Remote-Code-Execution.html https://www.zerodayinitiative.com/advisories/ZDI-20-335 • CWE-732: Incorrect Permission Assignment for Critical Resource •
CVSS: 8.8EPSS: 0%CPEs: 2EXPL: 3CVE-2020-10882 – TP-Link Archer A7 tdpServer Command Injection Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2020-10882
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of TP-Link Archer A7 Firmware Ver: 190726 AC1750 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the tdpServer service, which listens on UDP port 20002 by default. When parsing the slave_mac parameter, the process does not properly validate 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 the root user. • https://www.exploit-db.com/exploits/48331 https://github.com/lnversed/CVE-2020-10882 http://packetstormsecurity.com/files/157255/TP-Link-Archer-A7-C7-Unauthenticated-LAN-Remote-Code-Execution.html https://www.zerodayinitiative.com/advisories/ZDI-20-334 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •
CVSS: 9.8EPSS: 3%CPEs: 2EXPL: 0CVE-2020-10885 – TP-Link Archer A7 DNS Response Improper Input Validation Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2020-10885
This vulnerability allows remote attackers to execute arbitrary code on affected installations of TP-Link Archer A7 Firmware Ver: 190726 AC1750 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of DNS responses. The issue results from the lack of proper validation of DNS reponses prior to further processing. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the root user. • https://www.zerodayinitiative.com/advisories/ZDI-20-337 • CWE-20: Improper Input Validation •
