Specifically, when an HTTP/2 request surpasses the predetermined limits for headers configured within the server, the associated HTTP/2 stream isn't reset immediately. Instead, the reset action occurs only after all the headers within the request have been processed. This lapse in resetting the stream exposes the system to potential risks, as it allows malicious actors to exploit the delay in stream reset to carry out various attacks, such as header manipulation or resource exhaustion."], "mitigation": {"lang": "en:us", "value": "Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability."}, "name": "CVE-2024-24549", "package_state": [{"cpe": "cpe:/o:redhat:enterprise_linux:6", "fix_state": "Out of support scope", "package_name": "tomcat6", "product_name": "Red Hat Enterprise Linux 6"}, {"cpe": "cpe:/o:redhat:enterprise_linux:7", "fix_state": "Not affected", "package_name": "tomcat", "product_name": "Red Hat Enterprise Linux 7"}, {"cpe": "cpe:/o:redhat:enterprise_linux:8", "fix_state": "Will not fix", "package_name": "pki-deps:10.6/pki-servlet-engine", "product_name": "Red Hat Enterprise Linux 8"}, {"cpe": "cpe:/o:redhat:enterprise_linux:9", "fix_state": "Will not fix", "package_name": "pki-servlet-engine", "product_name": "Red Hat Enterprise Linux 9"}], "public_date": "2024-03-13T00:00:00Z", "references": ["https://www.cve.org/CVERecord?id=CVE-2024-24549\nhttps://nvd.nist.gov/vuln/detail/CVE-2024-24549\nhttps://lists.apache.org/thread/4c50rmomhbbsdgfjsgwlb51xdwfjdcvg"], "statement": "This vulnerability presents an Important severity issue due to its potential to facilitate various forms of attack, particularly in the context of HTTP/2 protocol. By delaying the reset of HTTP/2 streams until after processing all headers, malicious actors can exploit this window to execute header manipulation attacks, leading to potential data exfiltration, injection of malicious content, or server resource exhaustion. Furthermore, the delayed reset prolongs the exposure time of vulnerable systems, increasing the likelihood of successful exploitation.\nIn addition, Red Hat Certificate System 10.0 and Red Hat Enterprise Linux 8's Identity Management, are using a vulnerable version of Tomcat that is bundled into the pki-servlet-engine component. However, HTTP/2 is not enabled in such a configuration, and it is not possible to trigger the flaw in a supported setup.
