CVE-2026-83149 in Application Testing Suite
Summary
by MITRE • 09/16/2026
Vulnerability in Oracle Application Testing Suite. The supported version that is affected is 13.3.0.1. Easily exploitable vulnerability allows low privileged attacker having Test Manager for Web Apps privilege with network access via HTTP to compromise Oracle Application Testing Suite. While the vulnerability is in Oracle Application Testing Suite, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Application Testing Suite accessible data as well as unauthorized update, insert or delete access to some of Oracle Application Testing Suite accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Application Testing Suite. CVSS 3.1 Base Score 9.1 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:L).

The identified vulnerability resides within Oracle Application Testing Suite version 13.3.0.1, representing a critical security flaw that undermines the integrity and confidentiality of the application testing environment. This issue is classified as an easily exploitable vulnerability that requires low-privileged access to manifest its full destructive potential. Specifically, an attacker must possess Test Manager for Web Apps privileges and have network access via HTTP to initiate the attack vector. The presence of this weakness indicates a significant lapse in access control mechanisms or input validation within the web application testing components, allowing authenticated users with limited initial permissions to escalate their influence over the system beyond what is intended by the security architecture.
The operational impact of exploiting this vulnerability extends far beyond the immediate boundaries of Oracle Application Testing Suite itself. While the root cause lies within this specific product, the attack scope changes significantly due to potential lateral movement or shared resource dependencies with other connected systems and data stores. A successful exploitation allows an attacker to gain unauthorized access to critical data that is accessible through the suite. This includes sensitive test results, configuration files, credentials stored for testing purposes, and potentially proprietary application logic being tested. The ability to read this information constitutes a severe breach of confidentiality, exposing organizations to intellectual property theft or further reconnaissance activities against their broader IT infrastructure.
In addition to unauthorized data retrieval, the vulnerability permits attackers to perform unauthorized modifications to the accessible data within Oracle Application Testing Suite. This includes the ability to insert new records, update existing entries, or delete critical information. Such actions compromise the integrity of the testing environment and any downstream processes that rely on accurate test outcomes. For instance, an attacker could alter test scripts or results to mask malicious activity in production systems or introduce backdoors disguised as legitimate test configurations. This level of write access transforms a simple data leak into a potential vector for persistent threats and system manipulation, affecting the reliability of quality assurance workflows and potentially leading to defective software deployments if tampered with before release.
Furthermore, the vulnerability enables an attacker to cause a partial denial of service against Oracle Application Testing Suite. By consuming excessive resources or triggering error states through malformed requests, the availability of the testing platform can be degraded. This impacts development teams who rely on continuous integration and automated testing pipelines, leading to operational delays and increased costs associated with system recovery and maintenance. The combination of high confidentiality impact, moderate integrity impact, and low but present availability impact results in a CVSS 3.1 Base Score of 9.1, indicating an extremely critical severity level that demands immediate remediation attention from security operations teams.
From a classification perspective, this vulnerability aligns with CWE-269 Improper Privilege Management or CWE-862 Missing Authorization, as it allows low-privileged users to perform actions reserved for higher-level administrators. The attack vector corresponds to ATT&CK technique T1078 Valid Accounts, where the attacker leverages legitimate credentials that have been compromised or misconfigured. Additionally, if data manipulation is involved, it may relate to CWE-94 Improper Control of Generation of Code SQL Injection or similar injection flaws depending on the specific implementation details not fully disclosed in the summary. The network-based nature via HTTP suggests exposure through web interfaces rather than direct server access, highlighting risks associated with internet-facing applications that lack sufficient input sanitization and role-based access control enforcement.
Mitigation strategies must focus on immediate patching of Oracle Application Testing Suite to version 13.3.0.2 or later where the flaw is resolved. In environments where patching cannot be applied immediately, network segmentation should be enforced to restrict HTTP access to only trusted internal subnets and specific IP addresses associated with authorized testing personnel. Implementing strict Web Application Firewall rules can help detect and block anomalous patterns of data modification or excessive resource consumption indicative of exploitation attempts. Additionally, organizations should review the principle of least privilege applied to Test Manager for Web Apps accounts, ensuring that no user retains more permissions than strictly necessary for their role. Regular audits of access logs and monitoring for unusual data changes within the suite are essential for early detection of potential compromise activities related to this vulnerability.
