Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
MobSF 是一个用于移动应用安全测试的工具。在 4.5.1 版本之前， 中的解压缩功能在遇到超过 限制的归档成员时，虽然会记录一条日志说明该成员被跳过，但并未继续处理后续的归档成员。因此，经过身份验证的用户可以上传一个构造好的 ZIP 或 APK 文件，其中包含一个超大成员。在未达到 总大小限制的情况下，该超大成员仍会被解压到磁盘，可能导致磁盘空间耗尽，从而阻止进一步的扫描操作。此问题已在 4.5.1 版本中修复。

Vulnerability Title
MobSF: Zip Bomb Denial of Service via Per-File Size Limit Bypass in ZIP/APK Extraction
Source: CVE Program / CVE List V5
Vulnerability Description
MobSF is a mobile application security testing tool used. Prior to 4.5.1, the unzip function in mobsf/StaticAnalyzer/views/common/shared_func.py logs that an archive member exceeding ZIP_MAX_UNCOMPRESSED_FILE_SIZE is being skipped but does not continue to the next member, so an authenticated user can upload a crafted ZIP or APK whose oversized member is extracted to disk when the aggregate ZIP_MAX_UNCOMPRESSED_TOTAL_SIZE limit has not yet been reached, potentially exhausting disk space and preventing further scans. This issue is fixed in version 4.5.1.
