Security Bulletin
Summary
A race condition happened when a code sequence runs concurrently with other code, and the code sequence needs exclusive access to a shared resource, but a time window exists in which the shared resource can be modified by another code sequence. In security-critical code, a race condition have security implications, specially when a security decision is made on class state affected by a race condition. The Java language provides a simple primitive, synchronized blocks, for avoiding thread interference and memory consistency errors. Race conditions typically appear with class state (mutable fields, static or not) is used in methods without synchronization blocks. Objects of a class are said to be thread-safe when they always maintain a valid state, as observed by other objects, in multi-threaded environments. A traditional cause of race conditions in Java are classes in the standard library (JDK), and in particular the java.text.Format subclasses (like NumberFormat, MessageFormat, DateFormat or SimpleDateFormat), which are not thread-safe. This rule reports usages of methods in object fields of non thread-safe JDK classes, outside synchronized blocks. JavaDoc for such classes include a note on synchronization; for example, for java.text.SingleDateFormat: "Date formats are not synchronized. It is recommended to create separate format instances for each thread. If multiple threads access a format concurrently, it must be synchronized externally."
Vulnerability Details
CVEID: CVE-2024-41779
DESCRIPTION: IBM Engineering Systems Design Rhapsody - Model Manager 7.0.2 and 7.0.3 could allow a remote attacker to bypass security restrictions, caused by a race condition. By sending a specially crafted request, an attacker could exploit this vulnerability to remotely execute code.

Disclaimer
According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
