DescriptionCVE.org

A vulnerability was found in yzcheng90 X-SpringBoot up to 5.0 and classified as critical. Affected by this issue is the function uploadApk of the file /sys/oss/upload/apk of the component APK File Handler. The manipulation of the argument File leads to path traversal. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

AnalysisAI

Path traversal in yzcheng90 X-SpringBoot up to version 5.0 allows remote authenticated attackers with low privileges to write files outside the intended directory via the File parameter of the /sys/oss/upload/apk endpoint. Exploit code is publicly available, but EPSS indicates very low exploitation probability (0.10%) and no active exploitation is reported.
