Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2023-0315 is a command injection vulnerability, tracked as CWE-77, that affects the Froxlor web hosting control panel in versions prior to 2.0.8. The flaw resides in the GitHub repository froxlor/froxlor and received a CVSS 3.1 score of 8.8, reflecting network-accessible exploitation with low attack complexity and low required privileges.

An authenticated attacker with low-privileged access can supply crafted input that results in arbitrary command execution on the underlying host. Successful exploitation grants the attacker full control over confidentiality, integrity, and availability of the affected system, enabling outcomes such as remote code execution without user interaction.

Publicly available proof-of-concept exploits targeting versions 2.0.6 and 2.0.3 have been posted to Packet Storm, and a fix was merged in commit 090cfc26f2722ac3036cc7fd1861955bc36f065a. The associated huntr.dev report confirms the issue was disclosed through coordinated vulnerability handling, indicating that administrators should upgrade to 2.0.8 or later to eliminate the injection vector. The EPSS score has remained elevated near its peak of 0.9032.
