A modified, unauthenticated server can send an unterminated string during the establishment of Kerberos transport encryption. When a libpq client application has a Kerberos credential cache and doesn't explicitly disable option "gssencmode", a server can cause libpq to over-read and report an error message containing uninitialized bytes from and following its receive buffer. If libpq's caller somehow makes that message accessible to the attacker, this achieves a disclosure of the over-read bytes. We have not confirmed or ruled out viability of attacks that arrange for a crash or for presence of notable, confidential information in disclosed bytes.

Summary

When running vertx web applications that serve files using StaticHandler on Windows Operating Systems and Windows File Systems, if the mount point is a wildcard () then an attacker can exfiltrate any class path resource.

Details When computing the relative path to locate the resource, in case of wildcards, the code:

returns the user input (without validation) as the segment to lookup. Even though checks are performed to avoid escaping the sandbox, given that the input was not sanitized \ are not properly handled and an attacker can build a path that is valid within the classpath.

A flaw was found in maven. Repositories that are defined in a dependency’s Project Object Model (pom), which may be unknown to users, are used by default resulting in potential risk if a malicious actor takes over that repository or is able to insert themselves into a position to pretend to be that repository. The highest threat from this vulnerability is to data confidentiality and integrity.

gRPC could allow a remote attacker to obtain sensitive information, caused by a flaw when gRPC HTTP2 stack raised a header size exceeded error. By sending a specially crafted request, an attacker could exploit this vulnerability to obtain sensitive information, and use this information to launch further attacks against the affected system.

IBM Cloud Pak for Automation 18.0.0, 18.0.1, 18.0.2, 19.0.1, 19.0.2, 19.0.3, 20.0.1, 20.0.2, 20.0.3, 21.0.1, 21.0.2, 21.0.3, 22.0.1, and 22.0.2 is potentially vulnerable to CSV Injection. A remote attacker could execute arbitrary commands on the system, caused by improper validation of csv file contents. IBM X-Force ID: 259354.

Apache Commons Jelly could allow a remote attacker to bypass security restrictions, caused by improper handling of XML External Entity (XXE) entries when parsing to an XML file. By persuading a victim to open a jelly file containing a specially crafted custom doctype entity in a SYSTEM entity that contains a URL, an attacker could exploit this vulnerability to conduct XML External Entity (XXE) attacks.

IBM Business Automation Workflow is vulnerable to cross-site scripting. This vulnerability allows users to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session.
