Exploitation Conditions

Exploitation requires a valid low-privileged account on the Oracle Agile Product Lifecycle Management for Process 6.2.4 application and network HTTP access to its Product Quality Management component. The CVSS AC:H rating signals that attack success depends on specific, hard-to-meet conditions (e.g., particular application state, timing, or request configuration) beyond the attacker's direct control, limiting reliable repeatable exploitation. Limiting factors: authentication is mandatory (PR:L, so anonymous internet attackers cannot exploit it directly), only version 6.2.4 is listed as affected, no user interaction is needed (UI:N), and scope is unchanged (S:U). Deployments restricting network reach to the PLM interface and enforcing least-privilege accounts further reduce realistic risk.

Impact

This is a moderate-priority, not a drop-everything, vulnerability. The CVSS 3.1 base score is 6.4 (MEDIUM) with vector AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:L/A:L: network-reachable over HTTP, but exploitation is explicitly rated high-complexity (AC:H) and requires an existing low-privileged authenticated account (PR:L), which materially raises the bar against opportunistic mass exploitation. Impact is asymmetric - high confidentiality loss (C:H, 'complete access to all accessible data') but only limited integrity and availability effects (I:L/A:L, partial updates and partial DoS). No EPSS score was provided in the input, there is no CISA KEV listing, and no public exploit code was identified, so all exploitation signals are currently absent or unknown. One conflict to flag: the input Tag 'Authentication Bypass' contradicts the CVSS vector's PR:L (which requires valid privileges) and the description's 'low privileged attacker' wording - verify with Oracle, as this does not appear to be an unauthenticated bypass. Net: a credentialed, high-skill attacker could exfiltrate sensitive PLM data, but the AC:H + PR:L combination and absence of exploitation evidence place this well below actively-exploited critical flaws in remediation priority.

Exploit ScenarioDerived

A low-privileged user with a valid account on an internet- or intranet-reachable Oracle Agile PLM for Process 6.2.4 instance sends crafted HTTP requests to the Product Quality Management component, chaining a difficult-to-trigger flaw to read data beyond their authorization scope. Successful exploitation yields full read access to PLM data plus limited data tampering and a partial denial of service. No public proof-of-concept is known, and the high attack complexity means exploitation requires specific conditions and skill rather than a turnkey exploit.

AnalysisAIv1 – Oct 20, 2026

Authenticated low-privileged users with HTTP access to Oracle Agile Product Lifecycle Management for Process 6.2.4 can exploit a high-complexity flaw in the Product Quality Management component to gain broad read access to critical data, make limited unauthorized data changes, and trigger a partial denial of service. The issue carries a CVSS 3.1 base score of 6.4 (AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:L/A:L); the high attack-complexity rating means successful exploitation depends on conditions outside the attacker's direct control. No public exploit code or confirmed active exploitation (CISA KEV) was identified in the available intelligence at time of analysis.

RemediationAI

Apply the Oracle Critical Patch Update (October 2026) referenced at https://www.oracle.com/security-alerts/cpuoct2026.html; the provided data does not specify an exact fixed version beyond identifying 6.2.4 as affected, so validate the patched release in that advisory before deployment. Until patching is complete, restrict HTTP access to the Agile PLM for Process interface to trusted networks or VPN segments and enforce least-privilege accounts, accepting that this may inconvenience legitimate remote users and break integrations that depend on broader access. Monitor and rate-limit Product Quality Management requests for anomalous read or write patterns, with the trade-off of possible false positives and added latency; also review account permissions to remove unnecessary privileges, which may require workflow adjustments.

Technical ContextAI · show details

Oracle Agile PLM for Process is an enterprise product lifecycle and quality management platform; the affected Product Quality Management component handles quality records and related workflows exposed over HTTP. The provided CWE is not assigned, so the precise root-cause class is undisclosed; the CVSS vector indicates a network-reachable, high-complexity weakness that requires a valid low-privileged account (PR:L) and no user interaction (UI:N), with unchanged scope. Impact skews toward confidentiality (C:H) with lesser integrity and availability effects (I:L/A:L). The 'Authentication Bypass' tag in the source metadata should be treated cautiously: the assessed vector requires authentication rather than showing an anonymous bypass, and successful attacks depend on hard-to-meet application state or request conditions.

DescriptionCVE.org

Vulnerability in the Oracle Agile Product Lifecycle Management for Process product of Oracle Supply Chain (component: Product Quality Management). The supported version that is affected is 6.2.4. Difficult to exploit vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Agile Product Lifecycle Management for Process. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Agile Product Lifecycle Management for Process accessible data as well as unauthorized update, insert or delete access to some of Oracle Agile Product Lifecycle Management for Process accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Agile Product Lifecycle Management for Process. CVSS 3.1 Base Score 6.4 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:L/A:L).

Attack Technique

Authentication bypass attacks exploit flaws in the verification mechanisms that control access to systems and applications.

Denial of Service attacks render applications or systems unavailable by overwhelming resources or triggering failure conditions.
