CVE-2024-20953: High Vulnerability in Oracle Agile PLM

CVE-2024-20953 is a high-severity vulnerability affecting the Oracle Agile Product Lifecycle Management (PLM) software, specifically in version 9.3.6. This vulnerability allows low-privileged attackers with network access via HTTP to compromise the system. Successful exploitation can lead to a complete takeover of Oracle Agile PLM, making it essential for organizations to address this issue promptly.

The CVSS 3.1 Base Score for this vulnerability is 8.8, indicating a critical risk to confidentiality, integrity, and availability. The attack vector is classified as network-based with a low attack complexity, meaning that it is easily exploitable by attackers. As it stands, organizations should prioritize patching immediately to protect their systems from potential exploitation.

Currently, the vulnerability is known to be included in the CISA Known Exploited Vulnerabilities (KEV) catalog, which highlights its significance and the urgency for remediation. Organizations using Oracle Agile PLM are advised to apply the necessary updates and monitor any unusual activity on their systems.

In light of these factors, it is critical for organizations to assess their exposure to this vulnerability and implement mitigations as prescribed by the vendor. The risk to organizations includes unauthorized access and potential data loss, which could have severe implications for business operations.

Vulnerability Details

According to the official description, the vulnerability is characterized as a deserialization issue within the Oracle Agile PLM product, specifically in the Export component. The supported version affected is 9.3.6. The CVSS vector string for this vulnerability is (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), detailing high impacts on confidentiality, integrity, and availability.

The vulnerability was published on February 17, 2024, and is classified under CWE-502, which pertains to deserialization issues. Organizations running this version of the product should be aware of the potential risks and the need for immediate remediation.

Technical Analysis

The root cause of CVE-2024-20953 lies in improper handling of deserialization within the application. Attackers may leverage this flaw to send crafted HTTP requests that exploit the deserialization process, enabling them to execute arbitrary code or perform unauthorized actions within the system.

The attack vector is network-based, meaning an attacker does not need physical access to exploit this vulnerability. Furthermore, the attack complexity is low, and the privileges required are also low, which enhances the likelihood of successful exploitation. User interaction is not required for this vulnerability to be exploited.

In terms of impact, the confidentiality, integrity, and availability of the system may be significantly compromised, leading to unauthorized data access, loss of data integrity, and disruption of service. Organizations should be aware that such vulnerabilities can have a cascading effect on overall system security.

Risk & Impact Analysis

The real-world deployment risk associated with CVE-2024-20953 is substantial, especially for organizations that rely on Oracle Agile PLM for critical business operations. The nature of the vulnerability allows attackers to potentially gain control over the system, which can lead to data breaches, financial loss, and reputational damage.

The urgency assessment based on the CVSS score of 8.8 indicates that organizations should prioritize addressing this vulnerability in their patch management cycle. Given its inclusion in the KEV catalog, it is essential for security teams to take immediate action to mitigate the risks and apply the necessary patches.

Affected Versions

The affected version for this vulnerability is 9.3.6 of Oracle Agile PLM. Organizations are advised to upgrade to the latest patched version to mitigate risks associated with this vulnerability.

Mitigation & Remediation

Organizations should apply the necessary patches provided by Oracle to remediate this vulnerability. For those unable to apply patches, alternative mitigations should be considered, such as implementing additional network security controls to restrict access to the affected systems. Monitoring for unusual activity can also help identify potential exploitation attempts.

For further guidance, organizations may consider engaging in penetration testing to assess their security posture.

Detection Guidance

Organizations should monitor logs for indicators of exploitation attempts, such as unusual HTTP requests targeting the Oracle Agile PLM application. Behavioral anomalies, such as unexpected system changes or unauthorized access attempts, should also be investigated.

AppSecure Threat Intelligence Insight
