CVE-2022-35777

CVE-2022-35777 is a vulnerability that was discovered in 2022. It is a flaw in the design and implementation of certain software, which can allow an attacker to execute arbitrary code on affected systems. Specifically, this vulnerability affects a popular web server software called Apache Tomcat, which is widely used by organizations to host their web applications. The vulnerability occurs due to a weakness in the handling of HTTP/2 requests by Apache Tomcat. An attacker can send a specially crafted HTTP/2 request to a vulnerable server, which can cause it to crash or execute malicious code. This could potentially give the attacker complete control over the affected system, allowing them to steal sensitive data or launch further attacks. Upon discovery of the vulnerability, the Apache Software Foundation released a security update to address the issue. They also advised users to upgrade their installations of Apache Tomcat as soon as possible to mitigate the risk of exploitation. Users who were unable to upgrade immediately were advised to implement temporary workarounds to reduce their exposure to the vulnerability. Overall, the CVE-2022-35777 vulnerability highlights the importance of regularly updating software and promptly addressing known vulnerabilities to ensure the security of critical systems.
