Background
Apache CXF is an open-source web services framework that helps in building and developing services using frontend programming APIs. It provides support for various protocols and data formats, making it a versatile tool for creating web services. However, an issue has been identified in versions prior to 2.6.13 and 2.7.x before 2.7.10 that allows for the cleartext transmission of sensitive information when certain conditions are met.
Vulnerability Detail
The SymmetricBinding component in Apache CXF, when EncryptBeforeSigning is enabled and the UsernameToken policy is set to an EncryptedSupportingToken, transmits the UsernameToken in cleartext. This means that an attacker who can sniff the network traffic can obtain sensitive information, such as usernames and passwords. This vulnerability poses a risk to the confidentiality of user credentials and can potentially lead to unauthorized access to systems or data.
How To Fix
Fixed versions by release line
The minimum fixed version depends on the release line you run.

Workaround
If upgrading to a fixed version of Apache CXF is not immediately feasible, a possible workaround is to disable the EncryptBeforeSigning option or modify the UsernameToken policy to not use an EncryptedSupportingToken. However, it is important to note that these workarounds may have other security implications and should be carefully evaluated before implementation.
Conclusion
The identified vulnerability in Apache CXF allows for the cleartext transmission of sensitive information, putting user credentials at risk. To mitigate this vulnerability, it is crucial to upgrade to the recommended fixed versions of Apache CXF. Alternatively, carefully evaluate and implement the provided workarounds.

Versions prior to 2.6.13 and 2.7.x before 2.7.10 are affected by this vulnerability.
This vulnerability allows remote attackers to obtain sensitive information, such as usernames and passwords, by sniffing the network traffic. It poses a risk to the confidentiality of user credentials and can potentially lead to unauthorized access to systems or data.
To fix this vulnerability, it is recommended to upgrade to Apache CXF version 2.6.13 or later if using version 2.6.x, or version 2.7.10 or later if using version 2.7.x. Updating the Apache CXF dependency in the project's Maven pom.xml file to the appropriate version and rebuilding the project will address this vulnerability.
If upgrading to a fixed version of Apache CXF is not immediately feasible, a possible workaround is to disable the EncryptBeforeSigning option or modify the UsernameToken policy to not use an EncryptedSupportingToken. However, it is important to note that these workarounds may have other security implications and should be carefully evaluated before implementation.
