Vulnerability

Description

Exploiting the flexibility of XML, attackers can inject malicious data into an application’s processing stream by leveraging external entities. This technique manipulates the entity values to inject harmful content, compromising the security and integrity of the processed data.

Recommendation

To mitigate this vulnerability, it is essential to restrict the parsing library’s ability to resolve external entities and support XInclude features. By doing so, applications can safeguard against malicious code injection and unwanted content downloads.
