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.

A flaw was found in hibernate-validator's 'isValid' method in the org.hibernate.validator.internal.constraintvalidators.hv.SafeHtmlValidator class, which can be bypassed by omitting the tag ending in a less-than character. Browsers may render an invalid html, allowing HTML injection or Cross-Site-Scripting (XSS) attacks.

FasterXML jackson-databind 2.x before 2.9.8 might allow attackers to have unspecified impact by leveraging failure to block the axis2-transport-jms class from polymorphic deserialization.

FasterXML jackson-databind 2.x before 2.9.8 might allow attackers to have unspecified impact by leveraging failure to block the openjpa class from polymorphic deserialization.

FasterXML jackson-databind 2.x before 2.9.8 might allow attackers to have unspecified impact by leveraging failure to block the jboss-common-core class from polymorphic deserialization.

JBoss BPM Suite 6 is vulnerable to a reflected XSS via dashbuilder. Remote attackers can entice authenticated users that have privileges to access dashbuilder (usually admins) to click on links to /dashbuilder/Controller containing malicious scripts. Successful exploitation would allow execution of script code within the context of the affected user.

JBoss BRMS 6 and BPM Suite 6 are vulnerable to a stored XSS via business process editor. The flaw is due to an incomplete fix for CVE-2016-5398. Remote, authenticated attackers that have privileges to create business processes can store scripts in them, which are not properly sanitized before showing to other users, including admins.

JBoss BRMS 6 and BPM Suite 6 before 6.4.3 are vulnerable to a stored XSS via several lists in Business Central. The flaw is due to lack of sanitation of user input when creating new lists. Remote, authenticated attackers that have privileges to create lists can store scripts in them, which are not properly sanitized before showing to other users, including admins.

JBoss BRMS 6 and BPM Suite 6 before 6.4.3 are vulnerable to a reflected XSS via artifact upload. A malformed XML file, if uploaded, causes an error message to appear that includes part of the bad XML code verbatim without filtering out scripts. Successful exploitation would allow execution of script code within the context of the affected user.

It was discovered that the Dashbuilder login page as used in Red Hat JBoss BPM Suite before 6.4.2 and Red Hat JBoss Data Virtualization & Services before 6.4.3 could be opened in an IFRAME, which made it possible to intercept and manipulate requests. An attacker could use this flaw to trick a user into performing arbitrary actions in the Console (clickjacking).
