Deeper analysis

A vulnerability identified as CVE-2023-2377 affects the Web Management Interface component of Ubiquiti EdgeRouter X devices running firmware up to version 2.0.9-hotfix.6. The issue stems from improper handling of the name argument, which permits command injection as classified under CWE-77. It received a CVSS 3.1 score of 6.3 and was publicly disclosed with proof-of-concept details available.

An authenticated remote attacker with low-privileged access can supply crafted input to the affected parameter and execute arbitrary commands on the device, potentially leading to limited impacts on confidentiality, integrity, and availability. The attack requires no user interaction and can be launched over the network.

Public references consist of proof-of-concept repositories and vulnerability database entries that document the flaw and its exploitability, though no vendor advisory or patch information is included in the available sources. The associated EPSS score has remained flat at 0.1373 with no material increase since disclosure.
