QuickJS 安全漏洞
英文标题:
Type confusion in string addition in QuickJS
漏洞描述
中文描述:
QuickJS是QuickJS开源的一个小型且可嵌入的 Javascript 引擎。 QuickJS存在安全漏洞，该漏洞源于处理字符串加法操作时存在类型混淆，可能导致越界内存访问和内存损坏，进而执行任意代码。
英文描述:
A type confusion vulnerability exists in the handling of the string addition (+) operation within the QuickJS engine. * The code first checks if the left-hand operand is a string. * It then attempts to convert the right-hand operand to a primitive value using JS_ToPrimitiveFree. This conversion can trigger a callback (e.g., toString or valueOf). * During this callback, an attacker can modify the type of the left-hand operand in memory, changing it from a string to a different type (e.g., an object or an array). * The code then proceeds to call JS_ConcatStringInPlace, which still treats the modified left-hand value as a string. This mismatch between the assumed type (string) and the actual type allows an attacker to control the data structure being processed by the concatenation logic, resulting in a type confusion condition. This can lead to out-of-bounds memory access, potentially resulting in memory corruption and arbitrary code execution in the context of the QuickJS runtime.
