CVE-2024-8672
CriticalSummary
Wtyczka Widget Options dla WordPressa jest podatna na zdalne wykonanie kodu we wszystkich wersjach do 4.0.7 włącznie, poprzez funkcjonalność logiki wyświetlania. Problem wynika z braku filtrowania i sprawdzania uprawnień dla danych wejściowych przekazywanych do funkcji eval().
Risk Assessment
Atakujący z poziomem dostępu co najmniej 'contributor' może wykonać dowolny kod na serwerze, co stwarza poważne zagrożenie dla bezpieczeństwa systemu. Istnieje ryzyko, że pomimo wprowadzenia poprawek, problem może nie być w pełni załatwiony.
Recommendation
Zaleca się ograniczenie możliwości wykonywania poleceń tylko do administratorów oraz wdrożenie listy dozwolonych funkcji. Należy również monitorować system pod kątem potencjalnych pozostałych luk bezpieczeństwa.

Original NVD description (English source)
The Widget Options – The #1 WordPress Widget & Block Control Plugin plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 4.0.7 via the display logic functionality that extends several page builders. This is due to the plugin allowing users to supply input that will be passed through eval() without any filtering or capability checks. This makes it possible for authenticated attackers, with contributor-level access and above, to execute code on the server. Special note: We suggested the vendor implement an allowlist of functions and limit the ability to execute commands to just administrators, however, they did not take our advice. We are considering this patched, however, we believe it could still be further hardened and there may be residual risk with how the issue is currently patched.
