CVE-2019-6487

31
FAUCET Score

CVE-2019-6487 is a critical command injection vulnerability affecting TP-Link WDR Series routers, such as the TL-WDR5620 V3.0, through firmware v3. An authenticated attacker can achieve remote code execution by injecting shell metacharacters into the "citycode" field of the weather function. This vulnerability carries a high CVSS score of 8.8, indicating a network-based attack with low complexity, requiring only authenticated access, and leading to complete compromise of confidentiality, integrity, and availability. While no active exploitation or public exploit code (Metasploit, Nuclei, ExploitDB) has been identified, and community discussion is minimal, the high EPSS and FAUCET Risk Score suggest a significant potential for exploitation.
