Understanding CVE-2024-20953

The Nature of the Vulnerability

CVE-2024-20953 is identified as a high-severity deserialization vulnerability found in Oracle Agile PLM version 9.3.6. Deserialization vulnerabilities occur when a program converts untrusted data into executable objects. In this instance, attackers can send specially crafted HTTP requests that cause the system to improperly process input data, resulting in the execution of arbitrary code. This flaw allows low-privileged attackers to bypass authentication measures and fully compromise an enterprise system.

How the Flaw Works

At its core, the vulnerability resides in the Export component of Oracle Agile PLM. During the deserialization process, data that is not correctly validated may be turned into objects that the application inadvertently executes. This insecure handling of data can be exploited to run malicious code, opening the door for attackers to control systems remotely, steal sensitive data, or even disrupt business operations. The flaw is so severe that it has been added to CISA’s Known Exploited Vulnerabilities (KEV) catalogue, reflecting its technical impact and risk to global supply chains.

The Role of Oracle Agile PLM in Modern Industries

Importance of Agile PLM in Business Operations

Oracle Agile PLM is more than just software—it is a cornerstone for manufacturing, healthcare, and technology industries. Organizations use Agile PLM to manage everything from product blueprints and compliance documentation to quality control processes and design collaborations. Given the sensitive nature of the data stored and processed by Agile PLM, any security breach could have far-reaching consequences. For instance, a successful attack could lead to intellectual property theft, disruption of production lines, or even malicious code injection into software updates.

The Supply Chain Connection

The implications of a breach extend far beyond a single organization. Agile PLM systems are often integrated into broader supply chain management solutions. Therefore, a compromise in this system can quickly propagate attacks to downstream partners and stakeholders. The interconnectedness of supply chains means that even a localized vulnerability can have a cascading effect, potentially leading to widespread disruption. This reality underscores the importance of robust security measures and timely patching, as vulnerabilities in core systems like Agile PLM are desirable targets for cybercriminals.

Technical Deep Dive: Exploiting Deserialization Vulnerabilities

What Is Deserialization?

Deserialization converts serialized data (data that has been transformed into a format suitable for storage or transmission) back into its original object format. When untrusted data is involved, the process can be exploited if the system does not enforce strict checks. In CVE-2024-20953, attackers manipulate the deserialization process to inject malicious payloads, bypassing standard authentication mechanisms and gaining control over the affected system.

The Attack Mechanism

Attackers exploit the vulnerability by sending HTTP requests specifically crafted to target the Export module of Oracle Agile PLM. Once the malicious request is processed, the system inadvertently converts the data into an executable object under the attacker’s control. Even a low-privileged user without exceptional credentials can trigger a chain reaction leading to complete system compromise. The ability to execute arbitrary code through these attacks makes this vulnerability extremely dangerous.

Potential Impact of a Successful Attack

Data Exfiltration and Intellectual Property Theft

One of the primary concerns with CVE-2024-20953 is the risk of data exfiltration. Attackers can steal sensitive information, including product designs, compliance documents, and other intellectual property critical to an organization’s competitive edge. For companies in industries where intellectual property is a key asset, the loss or exposure of this information can result in significant financial and reputational damage.

Disruption of Critical Operations

Given the central role of Agile PLM in managing production lines and quality controls, any disruption caused by a successful attack can lead to operational downtime. Manufacturers might face halted production, while healthcare organizations could experience delays in delivering critical products or services. Such disruptions can have catastrophic consequences in sectors where time and precision are paramount.

Propagation of Attacks in the Supply Chain

The vulnerability’s integration into Oracle’s broader supply chain suite amplifies the potential risk. Once an Agile PLM system is compromised, attackers can leverage that access to launch attacks on connected systems and partners. This ripple effect makes proactive vulnerability management and immediate remediation even more critical for organizations across the supply chain.
