Deeper analysis

TOTOlink A7100RU firmware version V7.4cu.2313_B20191024 contains an OS command injection vulnerability (CWE-78) in the setting/setOpenVpnCertGenerationCfg function. The flaw is triggered by unsanitized input to the password parameter and carries a CVSS 3.1 score of 9.8, reflecting network-accessible exploitation without authentication or user interaction.

An unauthenticated attacker with network access to the device can supply a crafted password value that results in arbitrary command execution on the underlying system, enabling full compromise of confidentiality, integrity, and availability. Public references consist of proof-of-concept material hosted on GitHub that demonstrates the injection vector.

The EPSS score for this CVE stands at 0.1490 with no indicated rise from an earlier lower value. No vendor advisory, patch information, or confirmed in-the-wild exploitation details are present in the supplied references.
