IBM API Connect 5.0.0.0 and 5.0.8.4 is affected by a NoSQL Injection in MongoDB connector for the LoopBack framework. IBM X-Force ID: 148807.

IBM LoopBack (IBM API Connect 2018.1, 2018.4.1, 5.0.8.0, and 5.0.8.4) could allow an attacker to bypass authentication if the AccessToken Model is exposed over a REST API, it is then possible for anyone to create an AccessToken for any User provided they know the userId and can hence get access to the other user’s data / access to their privileges (if the user happens to be an Admin for example). IBM X-Force ID: 148801.

IBM API Connect 5.0.0.0 through 5.0.8.4 allows a user with limited 'API Administrator level access to give themselves full 'Administrator' level access through the members functionality. IBM X-Force ID: 153914.

IBM API Connect 2018.1 through 2018.3.7 could allow an unauthenticated attacker to cause a denial of service due to not setting limits on JSON payload size. IBM X-Force ID: 148802.

IBM API Connect 5.0.0.0, 5.0.8.4, 2018.1 and 2018.3.6 is vulnerable to CSV injection via the developer portal and analytics that could contain malicious commands that would be executed once opened by an administrator. IBM X-Force ID: 148692.

IBM API Connect v2018.1.0 through v2018.3.4 could allow an attacker to send a specially crafted request to conduct a server side request forgery attack. IBM X-Force ID: 148939.

NodeJS Tough-Cookie version 2.2.2 contains a Regular Expression Parsing vulnerability in HTTP request Cookie Header parsing that can result in Denial of Service. This attack appear to be exploitable via Custom HTTP header passed by client. This vulnerability appears to have been fixed in 2.3.0.

IBM API Connect 5.0.0.0 through 5.0.8.3 could allow a remote attacker to hijack the clicking action of the victim. By persuading a victim to visit a malicious Web site, a remote attacker could exploit this vulnerability to hijack the victim's click actions and possibly launch further attacks against the victim. IBM X-Force ID: 143744.

IBM API Connect's Developer Portal 5.0.0.0 through 5.0.8.3 is vulnerable to Server Side Request Forgery. An attacker, using specially crafted input parameters can trick the server into making potentially malicious calls within the trusted network. IBM X-Force ID: 146370.

IBM API Connect 5.0.0.0-5.0.8.3 Developer Portal does not enforce Two Factor Authentication (TFA) while resetting a user password but enforces it for all other login scenarios. IBM X-Force ID: 144483.
