Vulnerability Title
Bytecode Viewer v2.10.x Zip Slip
Vulnerability Description
Bytecode Viewer (BCV) is a Java/Android reverse engineering suite. Versions of the package prior to 2.11.0 are vulnerable to Arbitrary File Write via Archive Extraction (AKA "Zip Slip"). The vulnerability is exploited using a specially crafted archive that holds directory traversal filenames (e.g. ../../evil.exe). The Zip Slip vulnerability can affect numerous archive formats, including zip, jar, tar, war, cpio, apk, rar and 7z. The attacker can then overwrite executable files and either invoke them remotely or wait for the system or user to call them, thus achieving remote command execution on the victim’s machine. The impact of a Zip Slip vulnerability would allow an attacker to create or overwrite existing files on the filesystem. In the context of a web application, a web shell could be placed within the application directory to achieve code execution. All users should upgrade to BCV v2.11.0 when possible to receive a patch. There are no recommended workarounds aside from upgrading.

Vulnerability Title
Bytecode Viewer 路径遍历漏洞
Vulnerability Description
Bytecode Viewer是一个高级轻量级 Java/Android 逆向工程套件（反编译器、编辑器、调试器等）。 Bytecode Viewer 2.11.0之前版本存在路径遍历漏洞，该漏洞源于软件容易受到通过存档提取进行任意文件写入的攻击。该漏洞利用了一个保存目录遍历文件名(例如. .. ..evil.exe)。攻击者可利用该漏洞可以覆盖可执行文件并远程调用它们，或者等待系统或用户调用它们，从而实现远程命令执行。
