Jenkins Jenkins provides the `secretTextarea` form field for multi-line secrets. Jenkins 2.478 and earlier, LTS 2.462.2 and earlier does not redact multi-line secret values in error messages generated for form submissions involving the `secretTextarea` form field. This can result in exposure of multi-line secrets through those error messages, e.g., in the system log. Jenkins 2.479, LTS 2.462.3 redacts multi-line secret values in error messages generated for form submissions involving the `secretTextarea` form field.
Jenkins provides APIs for fine-grained control of item creation: - Authorization strategies can prohibit the creation of items of a given type in a given item group (`ACL#hasCreatePermission2`). - Item types can prohibit creation of new instances in a given item group (`TopLevelItemDescriptor#isApplicableIn(ItemGroup)`). If an attempt is made to create an item of a prohibited type through the Jenkins CLI or the REST API and either of the above checks fail, Jenkins 2.478 and earlier, LTS 2.462.2 and earlier creates the item in memory, only deleting it from disk. This allows attackers with Item/Create permission to bypass these restrictions, creating a temporary item. With Item/Configure permission, they can also save the item to persist it. If an attempt is made to create an item of a prohibited type through the Jenkins CLI or the REST API and either of the above checks fail, Jenkins 2.479, LTS 2.462.3 does not retain the item in memory.
In Spring Framework versions 5.3.0 - 5.3.38 and older unsupported versions, it is possible for a user to provide a specially crafted Spring Expression Language (SpEL) expression that may cause a denial of service (DoS) condition. Older, unsupported versions are also affected. Specifically, an application is vulnerable when the following is true: * The application evaluates user-supplied SpEL expressions.
Sydent is an identity server for the Matrix communications protocol. Prior to version 2.5.6, if configured to send emails using TLS, Sydent does not verify SMTP servers' certificates. This makes Sydent's emails vulnerable to interception via a man-in-the-middle (MITM) attack. Attackers with privileged access to the network can intercept room invitations and address confirmation emails. This is patched in Sydent 2.5.6. When patching, make sure that Sydent trusts the certificate of the server it is connecting to. This should happen automatically when using properly issued certificates. Those who use self-signed certificates should make sure to copy their Certification Authority certificate, or their self signed certificate if using only one, to the trust store of your operating system. As a workaround, one can ensure Sydent's emails fail to send by setting the configured SMTP server to a loopback or non-routable address under one's control which does not have a listening SMTP server.
