Oaklouds Custom Page 4 0
Monthly
Unauthenticated remote code execution affects HGiga's OAKlouds Custom Page module in the 2.0, 3.0 and 4.0 lines at builds below 26, where an attacker who can reach the Custom Page endpoint can submit malicious serialized content and have it deserialized into arbitrary code running with the web service's privileges. The CVSS 4.0 score of 9.3 reflects the worst case for an unauthenticated network attacker (PR:N, UI:N, AT:N, high confidentiality, integrity and availability impact on the vulnerable system), and the practical limiter is exposure - whether the affected instance is reachable from untrusted networks - rather than any technical precondition. No public exploit code has been identified at time of analysis and the flaw is not currently listed as confirmed actively exploited (CISA KEV), but the low attack complexity, unauthenticated access and full-system impact make this a genuinely high-priority issue for any organization running the affected builds, and a vendor fix is available.
