CVE-2023-28507 : Vulnerability Insights and Analysis

This CVE-2023-28507 involves a memory-exhaustion issue in the LZ4 decompression routine in UniRPC daemon, affecting Rocket Software's UniData and UniVerse versions.

Understanding CVE-2023-28507

This vulnerability impacts Rocket Software's UniData versions prior to 8.2.4 build 3003 and UniVerse versions prior to 11.3.5 build 1001 or 12.2.1 build 2002. The issue occurs when the decompression routine continuously allocates memory until the system's memory is depleted, leading to a crash of the forked process.

What is CVE-2023-28507?

CVE-2023-28507 is classified under CWE-400, indicating an uncontrolled resource consumption vulnerability. In this case, the LZ4 decompression routine does not properly manage memory allocation, resulting in excessive memory usage that can cause system instability and crashes.

The Impact of CVE-2023-28507

The impact of CVE-2023-28507 is significant as it can lead to denial of service (DoS) conditions where the affected process crashes due to memory exhaustion. This could potentially disrupt normal system operations and impact the availability of services relying on the affected Rocket Software products.

Technical Details of CVE-2023-28507

This vulnerability stems from a flaw in the LZ4 decompression routine used in UniRPC daemon in Rocket Software's UniData and UniVerse products. The issue arises in earlier versions of these products, creating a risk of memory exhaustion and subsequent process crashes.

Vulnerability Description

The vulnerability in CVE-2023-28507 allows a decompression routine to consume memory endlessly until all available system memory is utilized, leading to a crash in the forked process utilizing the routine. This uncontrolled resource consumption can be exploited by attackers to disrupt systems running the affected Rocket Software products.

Affected Systems and Versions

Rocket Software's UniData versions prior to 8.2.4 build 3003 and UniVerse versions prior to 11.3.5 build 1001 or 12.2.1 build 2002 are vulnerable to the memory-exhaustion issue caused by the LZ4 decompression routine. Organizations using these versions are at risk of facing the consequences of this vulnerability if left unaddressed.

Exploitation Mechanism

The vulnerability in CVE-2023-28507 can be exploited by malicious actors by triggering the decompression routine in the affected Rocket Software products. By attempting to decompress specially crafted payloads, attackers can exhaust the system's memory and cause crashes in the forked processes, leading to potential disruptions and system instability.

Mitigation and Prevention

To mitigate the risks associated with CVE-2023-28507, immediate actions need to be taken to secure systems running vulnerable UniData and UniVerse versions.

Immediate Steps to Take

Organizations should update Rocket Software's UniData to version 8.2.4 build 3003 or later, and UniVerse to version 11.3.5 build 1001 or 12.2.1 build 2002 to address the memory-exhaustion vulnerability.
Implement network security measures to monitor and detect any unusual memory consumption patterns that may indicate a potential exploit of the vulnerability.

Long-Term Security Practices

Regularly update and patch Rocket Software products to ensure the latest security fixes are in place.
Conduct thorough security assessments and audits to identify and address vulnerabilities within the organization's software and systems.

Patching and Updates

Applying the necessary patches and updates provided by Rocket Software for UniData and UniVerse is crucial in mitigating the risks posed by CVE-2023-28507. Timely patch management practices can help prevent exploitation of known vulnerabilities and enhance overall system security.
