Red Hat Security Advisory 2024-10385-03 - A security update is now available for Red Hat JBoss Enterprise Application Platform 8.0. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link in the References section.

**Impact** A Reflected Cross-Site Scripting (XSS) vulnerability was discovered in the authentication flow of the application. This issue arises due to improper sanitization of the URL parameters, allowing the URL bar's contents to be injected and reflected into the HTML page. An attacker could craft a malicious URL to execute arbitrary JavaScript in the browser of a victim who visits the link. **Who is impacted?** Any application utilizing this authentication library is vulnerable. Users of the application are at risk if they can be lured into clicking on a crafted malicious link. **Patches** The vulnerability has been patched in **2.5.5** by ensuring proper sanitization and escaping of user input in the affected URL parameters. Users are strongly encouraged to upgrade to the following versions: **Workarounds** If upgrading is not immediately possible, users can implement the following workarounds: - Employ a Web Application Firewall (WAF) to block malicious requests containing sus...

### Summary sigstore-java has insufficient verification for a situation where a validly-signed but "mismatched" bundle is presented as proof of inclusion into a transparency log ### Impact This bug impacts clients using any variation of KeylessVerifier.verify() The verifier may accept a bundle with an unrelated log entry, cryptographically verifying everything but fails to ensure the log entry applies to the artifact in question, thereby "verifying" a bundle without any proof the signing event was logged. This allows the creation of a bundle without fulcio certificate and private key combined with an unrelated but time-correct log entry to fake logging of a signing event. A malicious actor using a compromised identity may want to do this to prevent discovery via rekor's log monitors. The signer's identity will still be available to the verifier. The signature on the bundle must still be on the correct artifact for the verifier to pass. sigstore-gradle-plugin and sigstore-maven-pl...

A vulnerability was found in Keycloak. Deployments of Keycloak with a reverse proxy not using pass-through termination of TLS, with mTLS enabled, are affected. This issue may allow an attacker on the local network to authenticate as any user or client that leverages mTLS as the authentication mechanism.

### Summary Several cross-site scripting vulnerabilities existed in the `deno_doc` crate which lead to Self-XSS with `deno doc --html`. ### Details & PoC 1.) XSS in generated `search_index.js` `deno_doc` outputed a JavaScript file for searching. However, the generated file used `innerHTML` on unsanitzed HTML input. https://github.com/denoland/deno_doc/blob/dc556c848831d7ae48f3eff2ababc6e75eb6b73e/src/html/templates/pages/search.js#L120-L144 2.) XSS via property, method and enum names `deno_doc` did not sanitize property names, method names and enum names. ### Impact The first XSS most likely didn't have an impact since `deno doc --html` is expected to be used locally with own packages.

Ubuntu Security Notice 7124-1 - Andy Boothe discovered that the Networking component of OpenJDK 23 did not properly handle access under certain circumstances. An unauthenticated attacker could possibly use this issue to cause a denial of service. It was discovered that the Hotspot component of OpenJDK 23 did not properly handle vectorization under certain circumstances. An unauthenticated attacker could possibly use this issue to access unauthorized resources and expose sensitive information.

## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-jgwc-jh89-rpgq. This link is maintained to preserve external references. ## Original Description A vulnerability was found in the Keycloak Server. The Keycloak Server is vulnerable to a denial of service (DoS) attack due to improper handling of proxy headers. When Keycloak is configured to accept incoming proxy headers, it may accept non-IP values, such as obfuscated identifiers, without proper validation. This issue can lead to costly DNS resolution operations, which an attacker could exploit to tie up IO threads and potentially cause a denial of service. The attacker must have access to send requests to a Keycloak instance that is configured to accept proxy headers, specifically when reverse proxies do not overwrite incoming headers, and Keycloak is configured to trust these headers.

## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-5545-r4hg-rj4m. This link is maintained to preserve external references. ## Original Description A vulnerability was found in Keycloak. A user with high privileges could read sensitive information from a Vault file that is not within the expected context. This attacker must have previous high access to the Keycloak server in order to perform resource creation, for example, an LDAP provider configuration and set up a Vault read file, which will only inform whether that file exists or not.

## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-wq8x-cg39-8mrr. This link is maintained to preserve external references. ## Original Description A vulnerability was found in the Keycloak-services package. If untrusted data is passed to the SearchQueryUtils method, it could lead to a denial of service (DoS) scenario by exhausting system resources due to a Regex complexity.

## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-v7gv-xpgf-6395. This link is maintained to preserve external references. ## Original Description A flaw was found in Keycloak. This issue occurs because sensitive runtime values, such as passwords, may be captured during the Keycloak build process and embedded as default values in bytecode, leading to unintended information disclosure. In Keycloak 26, sensitive data specified directly in environment variables during the build process is also stored as a default values, making it accessible during runtime. Indirect usage of environment variables for SPI options and Quarkus properties is also vulnerable due to unconditional expansion by PropertyMapper logic, capturing sensitive data as default values in all Keycloak versions up to 26.0.2.
