Comprehensive Technical Analysis of EUVD-2025-6192

1. Vulnerability Assessment and Severity Evaluation

The vulnerability identified in the Edimax IC-7100 IP Camera (EUVD-2025-6192) is critical due to its potential for remote code execution (RCE). The CVSS (Common Vulnerability Scoring System) base score of 9.3 indicates a high severity level. The vector string CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N breaks down as follows:

• AV:N (Network): The vulnerability is exploitable over the network.
• AC:L (Low): The attack complexity is low, meaning it is relatively easy to exploit.
• AT:N (None): No special conditions are required for the attack.
• PR:N (None): No privileges are required to exploit the vulnerability.
• UI:N (None): No user interaction is required.
• VC:H (High): The vulnerability has a high impact on confidentiality.
• VI:H (High): The vulnerability has a high impact on integrity.
• VA:H (High): The vulnerability has a high impact on availability.
• SC:N (None): The scope of the vulnerability does not change.
• SI:N (None): The scope impact is not changed.
• SA:N (None): The scope availability is not changed.

The EPSS (Exploit Prediction Scoring System) score of 42 suggests a moderate likelihood of exploitation in the wild.
