A misconfiguration flaw was found in Keycloak. This issue can allow an attacker to redirect users to an arbitrary URL if a 'Valid Redirect URI' is set to http://localhost/ or http://127.0.0.1/, enabling sensitive information such as authorization codes to be exposed to the attacker, potentially leading to session hijacking.

A flaw exists in the SAML signature validation method within the Keycloak XMLSignatureUtil class. The method incorrectly determines whether a SAML signature is for the full document or only for specific assertions based on the position of the signature in the XML document, rather than the Reference element used to specify the signed element. This flaw allows attackers to create crafted responses that can bypass the validation, potentially leading to privilege escalation or impersonation attacks.

### Summary A DOM Clobbering gadget has been discoverd in Astro's client-side router. It can lead to cross-site scripting (XSS) in websites enables Astro's client-side routing and has *stored* attacker-controlled scriptless HTML elements (i.e., `iframe` tags with unsanitized `name` attributes) on the destination pages. ### Details #### Backgrounds DOM Clobbering is a type of code-reuse attack where the attacker first embeds a piece of non-script, seemingly benign HTML markups in the webpage (e.g. through a post or comment) and leverages the gadgets (pieces of js code) living in the existing javascript code to transform it into executable code. More for information about DOM Clobbering, here are some references: [1] https://scnps.co/papers/sp23_domclob.pdf [2] https://research.securitum.com/xss-in-amp4email-dom-clobbering/ #### Gadgets found in Astro We identified a DOM Clobbering gadget in Astro's client-side routing module, specifically in the `<ViewTransitions />` component. ...

Debian Linux Security Advisory 5791-1 - Elyas Damej discovered that a sandbox mechanism in ReportLab, a Python library to create PDF documents, could be bypassed which may result in the execution of arbitrary code when converting malformed HTML to a PDF document.

ABB Cylon Aspect version 3.08.00 suffers from an authenticated OS command injection vulnerability. This can be exploited to inject and execute arbitrary shell commands through the PROXY HTTP POST parameter called by the yumSettings.php script.

Cybersecurity researchers have found that entry points could be abused across multiple programming ecosystems like PyPI, npm, Ruby Gems, NuGet, Dart Pub, and Rust Crates to stage software supply chain attacks. "Attackers can leverage these entry points to execute malicious code when specific commands are run, posing a widespread risk in the open-source landscape," Checkmarx researchers Yehuda

Hey there, it's your weekly dose of "what the heck is going on in cybersecurity land" – and trust me, you NEED to be in the loop this time. We've got everything from zero-day exploits and AI gone rogue to the FBI playing crypto kingpin – it's full of stuff they don't 🤫 want you to know. So let's jump in before we get FOMO. ⚡ Threat of the Week GoldenJackal Hacks Air-Gapped Systems: Meet

pac4j is a security framework for Java. `pac4j-core` prior to version 4.0.0 is affected by a Java deserialization vulnerability. The vulnerability affects systems that store externally controlled values in attributes of the `UserProfile` class from pac4j-core. It can be exploited by providing an attribute that contains a serialized Java object with a special prefix `{#sb64}` and Base64 encoding. This issue may lead to Remote Code Execution (RCE) in the worst case. Although a `RestrictedObjectInputStream` is in place, that puts some restriction on what classes can be deserialized, it still allows a broad range of java packages and potentially exploitable with different gadget chains. pac4j versions 4.0.0 and greater are not affected by this issue. Users are advised to upgrade. There are no known workarounds for this vulnerability.

ABB Cylon Aspect version 3.07.02 uses a weak set of default administrative credentials that can be guessed in remote password attacks and used to gain full control of the system.

ABB Cylon Aspect version 3.08.00 suffers from an authenticated OS command injection vulnerability. This can be exploited to inject and execute arbitrary shell commands through the MODEM HTTP POST parameter called by the dialupSwitch.php script.
