MITRE ATT&CK
1 technique across 1 tactic: Defense Evasion The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | The attacker must have a valid low-privileged account AND local logon access to the infrastructure/host where Oracle Identity Manager executes (AV:L, PR:L) - the Installer component is the affected surface. No user interaction is required (UI:N). Only Oracle Identity Manager 12.2.1.4.0 and 14.1.2.1.0 are affected. The decisive limiting factor is that exploitation is purely local: it cannot be launched remotely over the network, so an attacker must first gain authenticated shell/console access to the OIM server, which sharply narrows realistic exposure to insiders or attackers who have already obtained a foothold on that host. |
| Impact | This is a medium-severity local information-disclosure flaw (CVSS 3.1 base 5.5) in the Installer component of Oracle Identity Manager, addressed as part of the Oracle Critical Patch Update of October 2026. The provided CVSS vector (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N) shows the key limiting factor clearly: exploitation requires local logon access to the host where OIM runs and a pre-existing low-privileged account - it is NOT remotely reachable. Impact is confined to confidentiality (C:H), with no integrity or availability effect. No EPSS exploitation-probability score was provided, the CVE is NOT listed in CISA KEV, and no public proof-of-concept is referenced, so the real-world exploitation signal is 'no public exploit identified at time of analysis.' Taken together, these signals point to a lower-priority, prerequisite-heavy issue rather than a mass-exploitation threat - patch on the normal Oracle CPU cadence with attention to multi-user/shared OIM hosts. CONFLICT TO NOTE: the input carries an 'Authentication Bypass' tag, but the CVSS vector requires authentication (PR:L) and the description explicitly requires a logged-on low-privileged attacker - this is an authenticated local disclosure, not an authentication bypass; treat the tag as unreliable. |
| Exploit ScenarioDerived | A low-privileged user who already has interactive logon access to the server hosting Oracle Identity Manager abuses a flaw in the Installer component to read critical data that OIM can access, resulting in unauthorized disclosure of sensitive identity information. Because the attack is local (AV:L) with low complexity (AC:L) and no user interaction, any authenticated local account on that host could trigger it. No public proof-of-concept is referenced in the available data. |

Alert meAnalysisAIv1 – Oct 20, 2026
Local information disclosure in Oracle Identity Manager 12.2.1.4.0 and 14.1.2.1.0 lets a low-privileged user who can log on to the host running OIM reach critical data through the Installer component, with a high confidentiality impact and no integrity or availability effect. Because the vector is strictly local (AV:L) and requires a valid low-privileged account (PR:L) with no user interaction (UI:N), this is primarily an insider or post-compromise risk rather than a remotely reachable attack surface. No public exploit code or confirmed active exploitation (CISA KEV) was identified at time of analysis, and Oracle addresses the flaw in its October 2026 Critical Patch Update; it is rated medium severity at CVSS 3.1 base 5.5.
RemediationAI
Apply the Oracle Critical Patch Update of October 2026 to Oracle Identity Manager 12.2.1.4.0 and 14.1.2.1.0 following the CPU advisory at https://www.oracle.com/security-alerts/cpuoct2026.html; the supplied data does not name a specific patched build number, so confirm the fixed release against the CPU's affected-version matrix before closing the finding. Until patching is complete, treat this as a local-only flaw and shrink the local attack surface: restrict interactive logon and shell access on OIM server hosts to a named, audited set of administrators (trade-off: tighter SSH/console access controls complicate break-glass and on-call procedures, so maintain a documented emergency account), and remove or permission-restrict installer working directories, staging files, response files and installation logs left behind after setup or patching, since these are the artifacts most consistent with an Installer-component confidentiality impact (trade-off: deleting installer state can hamper rollback and troubleshooting, so archive it to a restricted location instead of leaving it world-readable). Because exploitation requires a valid low-privileged account plus local logon (PR:L/AV:L), audit local and domain accounts that can reach the OIM host, review sudo/runas delegation granted to installer paths, and monitor for unexpected reads of OIM installation directories. Network controls, WAF rules and remote filtering do not mitigate this issue: the vector contains no AV:N component. Note that POC availability and active exploitation were not observed in the supplied intelligence, so prioritization should follow standard CPU cadence rather than emergency response, weighted by how many untrusted users hold local logon rights on OIM servers.

Technical ContextAI · show details
Oracle Identity Manager is the identity governance and provisioning component of Oracle Fusion Middleware, and this issue sits in its Installer component, the setup/patching subsystem that runs on the OIM server host and handles installation-time configuration and deployment artifacts. No CWE identifier was supplied in the source data, but the CVSS 3.1 vector (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N) defines the root-cause class operationally: a low-complexity, local-only path that yields full read access to data the OIM installation can reach, with no write or denial-of-service effect. Installer-surface bugs of this shape typically stem from artifacts left readable on the filesystem, insecure permissions on installation directories or configuration/credential files, or secrets captured in installer logs; those are inference from the vector rather than stated facts, since the advisory does not disclose the mechanism. Notably, the third-party tagging labels this an 'Authentication Bypass', which is not supported by the assessed vector - PR:L requires a valid low-privileged account, so the tag should be treated as unconfirmed vendor-agnostic tagging and not as evidence that unauthenticated access is possible. The affected scope is tightly bounded to OIM 12.2.1.4.0 and 14.1.2.1.0 on the host where the installer executes; no CPE strings were provided, so product matching must rely on the Oracle CPU affected-version matrix.

AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
Requires local logon so AV:L and a low-privileged account so PR:L; attack is straightforward (AC:L) and impact is data disclosure only, hence C:H with I:N and A:N.
