Possible local file exfiltration by XML External entity injection

Gradle is a build tool with a focus on build automation and support for multi-language development. In some cases, when Gradle parses XML files, resolving XML external entities is not disabled. Combined with an Out Of Band XXE attack (OOB-XXE), just parsing XML can lead to exfiltration of local text files to a remote server. Gradle parses XML files for several purposes. Most of the time, Gradle parses XML files it generated or were already present locally. Only Ivy XML descriptors and Maven POM files can be fetched from remote repositories and parsed by Gradle. In Gradle 7.6.3 and 8.4, resolving XML external entities has been disabled for all use cases to protect against this vulnerability. Gradle will now refuse to parse XML files that have XML external entities.

Gradle 代码问题漏洞

Gradle是美国Gradle公司的一套基于JVM的项目构建工具，它支持maven、Ivy仓库等。 Gradle 7.6.3之前 和 8.4之前版本存在代码问题漏洞，该漏洞源于在某些情况下，当 Gradle 解析 XML 文件时，不会禁用解析 XML 外部实体，与带外 XXE 攻击 (OOB-XXE) 相结合，仅解析 XML 就可能导致本地文本文件渗透到远程服务器。
