vul_other:java_ghost_bits_bypass（Rule ID：1070310268）

Release Date：2026/4/30

Rule Name：JAVA Ghost Bits Bypass Attack

Severity：high

CVE ID：CVE-2025-41242

 

Descripiton：

Some Java backends employ methods that trigger explicit type casting, leading to high-bit truncation where only the low-order 8 bits are retained. Attackers exploit this by crafting 'ghost text'—a sequence of Unicode characters or symbols whose low-order bits match malicious ASCII commands—effectively bypassing security detection mechanisms.This rule detects directory traversal attack attempts that exploit Ghost Bits for bypass. This rule supports to defend the A6: Vulnerable and Outdated Components of OWASP Top 10 - 2021.
Other reference：None

 

Solution：

Update vendor patches.
