The proxied request path is improperly parsed, allowing an attacker to change the scheme and host of the request. This leads to SSRF, and could potentially lead to sensitive data exposure. ### Details The `new URL` constructor is used to parse the final path. This constructor can be passed a relative scheme or path in order to change the host the request is sent to. This constructor is also very tolerant of poorly formatted URLs. As a result we can pass a path prefixed with the string `http:`. This has the effect of changing the scheme to HTTP. We can then subsequently pass a new host, for example `http:127.0.0.1:8080`. This would allow us to send requests to a local server. ### PoC Make a request to `/api/_nuxt_icon/http:example.com`, observe the data returned has been fetched from a different resource than intended. I typically try to find an example within N...

The APT used DNS poisoning to install the Macma backdoor on targeted networks and then deliver malware to steal data via post-exploitation activity.

Experts say the “nonsensical” policy proposal, which largely aligns with Donald Trump’s agenda, would weaken the US agency tasked with protecting election integrity, critical infrastructure, and more.

Incident response is a structured approach to managing and addressing security breaches or cyber-attacks. Security teams must overcome challenges such as timely detection, comprehensive data collection, and coordinated actions to enhance readiness. Improving these areas ensures a swift and effective response, minimizing damage and restoring normal operations quickly. Challenges in incident

Ubuntu Security Notice 6926-2 - 黄思聪 discovered that the NFC Controller Interface implementation in the Linux kernel did not properly handle certain memory allocation failure conditions, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service. It was discovered that a race condition existed in the Bluetooth subsystem in the Linux kernel when modifying certain settings values through debugfs. A privileged local attacker could use this to cause a denial of service.

A privileged local attacker could use this to cause a denial of service. Chenyuan Yang discovered that the Unsorted Block Images flash device volume management subsystem did not properly validate logical eraseblock sizes in certain situations. An attacker could possibly use this to cause a denial of service.

The lesson for users, especially if you’re a private company that primarily uses GitHub, is just to understand the inherent dangers of using open-source software.

Mattermost versions 9.9.x <= 9.9.0, 9.5.x <= 9.5.6, 9.7.x <= 9.7.5, 9.8.x <= 9.8.1 fail to properly validate synced posts, when shared channels are enabled,  which allows a malicious remote to create/update/delete arbitrary posts in arbitrary channels
