CVE-2020-10111

Citrix Gateway 11.1, 12.0, and 12.1 has an Inconsistent Interpretation of HTTP Requests. NOTE: Citrix disputes the reported behavior as not a security issue. Citrix ADC only caches HTTP/1.1 traffic for performance optimization...

CVE-2019-18678

An issue was discovered in Squid 3.x and 4.x through 4.8. It allows attackers to smuggle HTTP requests through frontend software to a Squid instance that splits the HTTP Request pipeline differently. The resulting Response messages corrupt caches between a client and Squid with attacker-controlle...

Privilege Escalation

silverstripe/framework is vulnerable to privilege escalation. Due to incorrectly shared caches between files and page content, CMS users with different permissions for these object types could gain more access than defined by the system...

Node.js third-party modules: Filesystem Writes via `yarn install` via symlinks and tar transforms inside a crafted malicious package

I would like to report an arbitrary filesystem write vulnerability in Yarn when installing a malicious package from the default repositories. This vulnerability has the potential for RCE -- even if --ignore-scripts is disabled. It allows a malicious package, upon install, to write to any path on...

Golang Go CVE-2019-16276 HTTP Request Smuggling Vulnerability

Description Golang Go is prone to an HTTP-request-smuggling vulnerability. A remote attacker may leverage this issue to poison web caches,bypass security defenses, launch cross-site scripting and HTML-injection attacks, and execute session-hijacking attacks. Other attacks are also possible...

The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has kernel packages installed that are affected by multiple vulnerabilities: - A use-after-free vulnerability was found in the way the Linux kernel's KVM hypervisor emulates a preemption timer for L2 guests when nested =1...

Side-channel Attack

httpd is vulnerable to side-channel attack. An implementation flaw was discovered in multiple cryptographic libraries that allows a side-channel based attacker to recover ECDSA or DSA private keys. When these cryptographic libraries use the private key to create a signature, such as for a TLS or...
