OpenClinic GA versions 5.09.02 and 5.89.05b may allow an attacker to bypass client-side access controls or use a crafted request to initiate a session with limited functionality, which may allow execution of admin functions such as SQL queries.

OpenClinic GA versions 5.09.02 and 5.89.05b may allow an attacker to bypass the system’s account lockout protection, which may allow brute force password attacks.

OpenClinic GA versions 5.09.02 and 5.89.05b do not properly check permissions before executing SQL queries, which may allow a low-privilege user to access privileged information.

OpenClinic GA versions 5.09.02 and 5.89.05b contain an authentication mechanism within the system that does not provide sufficient complexity to protect against brute force attacks, which may allow unauthorized users to access the system after no more than a fixed maximum number of attempts.

In Eclipse OpenJ9 prior to version 0.21 on Power platforms, calling the System.arraycopy method with a length longer than the length of the source or destination array can, in certain specially crafted code patterns, cause the current method to return prematurely with an undefined return value. This allows whatever value happens to be in the return register at that time to be used as if it matches the method's declared return type.

In all versions of Eclipse Web Tools Platform through release 3.18 (2020-06), XML and DTD files referring to external entities could be exploited to send the contents of local files to a remote server when edited or validated, even when external entity resolution is disabled in the user preferences.

In Eclipse Jetty, versions 9.4.27.v20200227 to 9.4.29.v20200521, in case of too large response headers, Jetty throws an exception to produce an HTTP 431 error. When this happens, the ByteBuffer containing the HTTP response headers is released back to the ByteBufferPool twice. Because of this double release, two threads can acquire the same ByteBuffer from the pool and while thread1 is about to use the ByteBuffer to write response1 data, thread2 fills the ByteBuffer with other data. Thread1 then proceeds to write the buffer that now contains different data. This results in client1, which issued request1 seeing data from another request or response which could contain sensitive data belonging to client2 (HTTP session ids, authentication credentials, etc.). If the Jetty version cannot be upgraded, the vulnerability can be significantly reduced by configuring a responseHeaderSize significantly larger than the requestHeaderSize (12KB responseHeaderSize and 8KB requestHeaderSize).

OpenClinic GA 5.09.02 and 5.89.05b stores passwords using inadequate hashing complexity, which may allow an attacker to recover passwords using known password cracking techniques.

OpenClinic GA 5.09.02 and 5.89.05b includes arbitrary local files specified within its parameter and executes some files, which may allow disclosure of sensitive files or the execution of malicious uploaded files.

An attacker may bypass permission/authorization checks in OpenClinic GA 5.09.02 and 5.89.05b by ignoring the redirect of a permission failure, which may allow unauthorized execution of commands.
