Deserialization of Untrusted Data

FasterXML jackson-databind through 2.8.11 and 2.9.x through 2.9.3 allows unauthenticated remote code execution because of an incomplete fix for the CVE-2017-7525 and CVE-2017-17485 deserialization flaws. This is exploitable via two different gadgets that bypass a blacklist.Show less

When an application with unsupported Codehaus versions of Groovy from 1.7.0 to 2.4.3, Apache Groovy 2.4.4 to 2.4.7 on classpath uses standard Java serialization mechanisms, e.g. to communicate between servers or to store local data, it was possible for an attacker to bake a special serialized object that will execute code directly when deserialized. All applications which rely on serialization and do not isolate the code which deserializes objects were subject to this vulnerability.Show less

FasterXML jackson-databind through 2.8.10 and 2.9.x through 2.9.3 allows unauthenticated remote code execution because of an incomplete fix for the CVE-2017-7525 deserialization flaw. This is exploitable by sending maliciously crafted JSON input to the readValue method of the ObjectMapper, bypassing a blacklist that is ineffective if the Spring libraries are available in the classpath.Show less

Previous versions of Apache Flex BlazeDS (4.7.2 and earlier) did not restrict which types were allowed for AMF(X) object deserialization by default. During the deserialization process code is executed that for several known types has undesired side-effects. Other, unknown types may also exhibit such behaviors. One vector in the Java standard library exists that allows an attacker to trigger possibly further exploitable Java deserialization of untrusted data. Other known vectors in third party libraries can be used to trigger remote code execution.Show less

In vBulletin through 5.3.x, there is an unauthenticated deserialization vulnerability that leads to arbitrary file deletion and, under certain circumstances, code execution, because of unsafe usage of PHP's unserialize() in vB_Library_Template's cacheTemplates() function, which is a publicly exposed API. This is exploited with the templateidlist parameter to ajax/api/template/cacheTemplates.Show less

A vulnerability in Swagger-Parser's version <= 1.0.30 and Swagger codegen version <= 2.2.2 yaml parsing functionality results in arbitrary code being executed when a maliciously crafted yaml Open-API specification is parsed. This in particular, affects the 'generate' and 'validate' command in swagger-codegen (<= 2.2.2) and can lead to arbitrary code being executed when these commands are used on a well-crafted yaml specification.Show less

In Pivotal Spring AMQP versions prior to 1.7.4, 1.6.11, and 1.5.7, an org.springframework.amqp.core.Message may be unsafely deserialized when being converted into a string. A malicious payload could be crafted to exploit this and enable a remote code execution attack.Show less

An issue was discovered in Pivotal Spring Security 4.2.0.RELEASE through 4.2.2.RELEASE, and Spring Security 5.0.0.M1. When configured to enable default typing, Jackson contained a deserialization vulnerability that could lead to arbitrary code execution. Jackson fixed this vulnerability by blacklisting known "deserialization gadgets." Spring Security configures Jackson with global default typing enabled, which means that (through the previous exploit) arbitrary code could be executed if all of the following is true: (1) Spring Security's Jackson support is being leveraged by invoking SecurityJackson2Modules.getModules(ClassLoader) or SecurityJackson2Modules.enableDefaultTyping(ObjectMapper); (2) Jackson is used to deserialize data that is not trusted (Spring Security does not perform deserialization using Jackson, so this is an explicit choice of the user); and (3) there is an unknown (Jackson is not blacklisting it already) "deserialization gadget" that allows code execution present on the classpath. Jackson provides a blacklisting approach to protecting against this type of attack, but Spring Security should be proactive against blocking unknown "deserialization gadgets" when Spring Security enables default typing.Show less

Red Hat JBoss A-MQ 6.x; BPM Suite (BPMS) 6.x; BRMS 6.x and 5.x; Data Grid (JDG) 6.x; Data Virtualization (JDV) 6.x and 5.x; Enterprise Application Platform 6.x, 5.x, and 4.3.x; Fuse 6.x; Fuse Service Works (FSW) 6.x; Operations Network (JBoss ON) 3.x; Portal 6.x; SOA Platform (SOA-P) 5.x; Web Server (JWS) 3.x; Red Hat OpenShift/xPAAS 3.x; and Red Hat Subscription Asset Manager 1.3 allow remote attackers to execute arbitrary commands via a crafted serialized Java object, related to the Apache Commons Collections (ACC) library.Show less

Mahara 15.04 before 15.04.8 and 15.10 before 15.10.4 and 16.04 before 16.04.2 are vulnerable to PHP code execution as Mahara would pass portions of the XML through the PHP "unserialize()" function when importing a skin from an XML file.Show less

The Reporting Compatibility Add On before 2.0.4 for OpenMRS, as distributed in OpenMRS Reference Application before 2.6.1, does not authenticate users when deserializing XML input into ReportSchema objects. The result is that remote unauthenticated users are able to execute operating system commands by crafting malicious XML payloads, as demonstrated by a single admin/reports/reportSchemaXml.form request.Show less
