CVE-2021-45450
HighCVSS 7.5Summary
W Mbed TLS przed wersją 2.28.0 oraz 3.x przed wersją 3.1.0, funkcje psa_cipher_generate_iv i psa_cipher_encrypt mogą umożliwiać obejście polityki lub odszyfrowanie oparte na oracle, gdy bufor wyjściowy znajduje się w lokalizacjach pamięci dostępnych dla nieufnej aplikacji.
Risk Assessment
Organizacja może być narażona na nieautoryzowany dostęp do danych, co może prowadzić do ujawnienia poufnych informacji lub naruszenia integralności danych.
Recommendation
Zaleca się aktualizację Mbed TLS do najnowszej wersji, aby usunąć tę podatność oraz monitorowanie aplikacji w celu wykrycia potencjalnych prób wykorzystania tej luki.

Joomla Extension - balbooa.com - Unauthenticated RCE via field shortcode injection in Balbooa Forms < 2.4.3.4 - Balbooa Forms supports administrator-defined PHP code which runs after a public form submission. The feature also supports form-field shortcodes inside that PHP. Before calling `eval()`, the component replaces each shortcode with the raw value submitted by the visitor, leading to an RCE vector. A public form must use the product's optional PHP-after-submission action and interpolate an attacker-controlled field shortcode inside a double-quoted PHP string to be vulnerable.

Fumasoft Fumeng Cloud contains a SQL injection vulnerability in the AjaxMethod.ashx endpoint that allows unauthenticated remote attackers to inject arbitrary SQL through the Name parameter of the getEmpByname action without any authentication. Attackers can exploit UNION-based SQL injection techniques against the Microsoft SQL Server backend to extract, disclose, and modify database contents, with potential for further compromise of the underlying server. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-18.

Original NVD description (English source)
