An attacker could exploit this vulnerability by sending renegotiation requests at a high rate. The vulnerability is due to improper handling of Secure Sockets Layer (SSL) renegotiation requests. For a detailed explanation of the JRE behaviour, see Markus Wulftange's blog () and this archived MSDN blog ().Ī vulnerability in the web interface of Cisco Identity Services Engine (ISE) could allow an unauthenticated, remote attacker to trigger high CPU usage, resulting in a denial of service (DoS) condition. The CGI option enableCmdLineArguments is disable by default in Tomcat 9.0.x (and will be disabled by default in all versions in response to this vulnerability). When running on Windows with enableCmdLineArguments enabled, the CGI Servlet in Apache Tomcat 9.0.0.M1 to 9.0.17, 8.5.0 to 8.5.39 and 7.0.0 to 7.0.93 is vulnerable to Remote Code Execution due to a bug in the way the JRE passes command line arguments to Windows. Please note that some of the information in the bulletin is compiled from external, open-source reports and is not a direct result of CISA analysis.Īpache PDFBox 2.0.14 does not properly initialize the XML parser, which allows context-dependent attackers to conduct XML External Entity (XXE) attacks via a crafted XFDF.

Patch information is provided when available. This information may include identifying information, values, definitions, and related links. Low: vulnerabilities with a CVSS base score of 0.0–3.9Įntries may include additional information provided by organizations and efforts sponsored by CISA.Medium: vulnerabilities with a CVSS base score of 4.0–6.9.High: vulnerabilities with a CVSS base score of 7.0–10.0.The division of high, medium, and low severities correspond to the following scores:

Vulnerabilities are based on the Common Vulnerabilities and Exposures (CVE) vulnerability naming standard and are organized according to severity, determined by the Common Vulnerability Scoring System (CVSS) standard. Please visit NVD for updated vulnerability entries, which include CVSS scores once they are available. In some cases, the vulnerabilities in the bulletin may not yet have assigned CVSS scores. The CISA Vulnerability Bulletin provides a summary of new vulnerabilities that have been recorded by the National Institute of Standards and Technology (NIST) National Vulnerability Database (NVD) in the past week.
