jQuery before 3.4.0, as used in Drupal, Backdrop CMS, and other products, mishandles jQuery.extend(true, {}, ...) because of Object.prototype pollution. If an unsanitized source object contained an enumerable __proto__ property, it could extend the native Object.prototype.

A Spring MVC or Spring WebFlux application running on JDK 9+ may be vulnerable to remote code execution (RCE) via data binding. The specific exploit requires the application to run on Tomcat as a WAR deployment. If the application is deployed as a Spring Boot executable jar, i.e. the default, it is not vulnerable to the exploit. However, the nature of the vulnerability is more general, and there may be other ways to exploit it.

When running Apache Tomcat versions 9.0.0.M1 to 9.0.0, 8.5.0 to 8.5.22, 8.0.0.RC1 to 8.0.46 and 7.0.0 to 7.0.81 with HTTP PUTs enabled (e.g. via setting the readonly initialisation parameter of the Default servlet to false) it was possible to upload a JSP file to the server via a specially crafted request. This JSP could then be requested and any code it contained would be executed by the server.

Apache Log4j2 versions 2.0-alpha1 through 2.16.0 (excluding 2.12.3 and 2.3.1) did not protect from uncontrolled recursion from self-referential lookups. This allows an attacker with control over Thread Context Map data to cause a denial of service when a crafted string is interpreted. This issue was fixed in Log4j 2.17.0, 2.12.3, and 2.3.1.

A vulnerability was found in Hibernate-Validator. The SafeHtml validator annotation fails to properly sanitize payloads consisting of potentially malicious code in HTML comments and instructions. This vulnerability can result in an XSS attack.

Multiple unspecified vulnerabilities in Cisco Unified Service Monitor before 8.6, as used in Unified Operations Manager before 8.6 and CiscoWorks LAN Management Solution 3.x and 4.x before 4.1; and multiple EMC Ionix products including Application Connectivity Monitor (Ionix ACM) 2.3 and earlier, Adapter for Alcatel-Lucent 5620 SAM EMS (Ionix ASAM) 3.2.0.2 and earlier, IP Management Suite (Ionix IP) 8.1.1.1 and earlier, and other Ionix products; allow remote attackers to execute arbitrary code via crafted packets to TCP port 9002, aka Bug IDs CSCtn42961 and CSCtn64922, related to a buffer overflow.

Directory traversal vulnerability in the TFTP service in Cisco CiscoWorks Common Services (CWCS) 3.0.x through 3.2.x on Windows, as used in Cisco Unified Service Monitor, Security Manager, TelePresence Readiness Assessment Manager, Unified Operations Manager, Unified Provisioning Manager, and other products, allows remote attackers to access arbitrary files via unspecified vectors.
