Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.

Description

A weakness has been identified in ulisesbocchio jasypt-spring-boot up to 3.0.5/4.0.4. Affected by this vulnerability is the function getSecretKeySaltGenerator of the file jasypt-spring-boot/src/main/java/com/ulisesbocchio/jasyptspringboot/encryptor/SimpleGCMConfig.java of the component Password Hash Handler. Executing a manipulation can lead to use of a one-way hash with a predictable salt. The attack can be launched remotely. The attack requires a high level of complexity. The exploitation appears to be difficult. The exploit has been made available to the public and could be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.
