A vulnerability was found in hansonwang99 Spring-Boot-In-Action up to 807fd37643aa774b94fd004cc3adbd29ca17e9aa. It has been declared as critical. Affected by this vulnerability is the function watermarkTest of the file /springbt_watermark/src/main/java/cn/codesheep/springbt_watermark/service/ImageUploadService.java of the component File Upload. The manipulation of the argument filename leads to path traversal. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. This product takes the approach of rolling releases to provide continious delivery. Therefore, version details for affected and updated releases are not available. The vendor was contacted early about this disclosure but did not respond in any way.
AnalysisAI
Path traversal vulnerability in Spring-Boot-In-Action up to commit 807fd37643aa774b94fd004cc3adbd29ca17e9aa allows remote authenticated attackers to read or write arbitrary files via the filename parameter in the watermarkTest function. Public exploit code exists, but EPSS score is low (0.07%) and no active exploitation has been reported.
Technical ContextAI
The vulnerability is a path traversal (CWE-22) in a Spring Boot application's file upload functionality. The affected component is the ImageUploadService.java file, which handles file uploads without properly sanitizing user-supplied filenames. This allows an attacker to manipulate the filename argument to traverse directories outside the intended upload directory. The product uses rolling releases, so specific version numbers are not available; the affected commit is 807fd37643aa774b94fd004cc3adbd29ca17e9aa.
RemediationAI
No official patch is available as the vendor did not respond. Users should apply input validation to sanitize filenames, restrict file upload paths, and use a whitelist of allowed characters. Alternatively, disable the watermarkTest endpoint if not needed. Monitor for any updates from the vendor.
