Description
Vulnerability in Oracle Trusted Answer Search (component: Application expert UI). The supported version that is affected is 26.1. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Trusted Answer Search. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Trusted Answer Search, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Trusted Answer Search accessible data as well as unauthorized access to critical data or complete access to all Oracle Trusted Answer Search accessible data. CVSS 3.1 Base Score 8.7 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:N).

Score: 8.7 High
EPSS: < 1% Very Low
KEV: No
Impact: Unauthorized data modification and unauthorized access to all application data.
Action: Immediate Patch
AI Analysis

Impact

The flaw in Oracle Trusted Answer Search’s Application expert UI lets an attacker with low privileges and network access over HTTP compromise the system. Successful exploitation requires a user other than the attacker to interact, usually through a web request or click, enabling the attacker to create, delete, or modify critical data or gain full read access to all data held by the application, thereby undermining confidentiality and integrity.

Affected Systems

Oracle Trusted Answer Search version 26.1 is affected. The vulnerability exists solely in this product and version. No other products or versions are listed as impacted, but attacks may propagate to additional Oracle products accessed via the same UI.

Risk and Exploitability

The CVSS 3.1 base score of 8.7 highlights a high‑severity flaw with substantial confidentiality and integrity effects. Exploitation requires only a low‑privilege account and network connectivity, but user interaction limits automation opportunities, suggesting that social engineering or phishing tactics could be used. EPSS data is unavailable and the issue is not cataloged in CISA KEV, yet the combination of wide network exposure and low privilege makes it a tangible risk for systems with an exposed Application expert UI.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Apply Oracle’s patch for version 26.1 as detailed in the official security advisory.
  • Restrict HTTP access to the Oracle Trusted Answer Search application to internal networks or VPN connections, limiting exposure to untrusted users.
  • Enforce strict role‑based access controls so that only authorized personnel can perform data‑creation, deletion, or modification operations, and ensure that low‑privileged users cannot bypass these controls.
  • Monitor application logs for anomalous data changes or unauthorized access attempts and investigate any suspicious activity promptly.
