Exploitation Conditions

The exploitable surface is Oracle HTTP Server's mod_ssl (HTTPS/TLS) interface, so the server must be reachable over HTTP/HTTPS by the attacker - the CVSS vector AV:N/AC:L/PR:N/UI:N indicates no authentication, no user interaction, and low complexity against network-facing OHS instances running affected versions 12.2.1.4.0 or 14.1.2.0.0. The concrete prerequisite is an internet- or network-reachable OHS listener served by the vulnerable mod_ssl module; the primary limiting factor is network exposure - instances confined to trusted internal segments or fronted by an independent authenticating proxy are substantially harder to reach, and only the two named supported versions are confirmed affected in the input.

Impact

The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N, base 9.1) describes a network-reachable, low-complexity, unauthenticated, no-user-interaction attack with high confidentiality and integrity impact and no availability impact - a genuinely high-priority profile. No EPSS score, SSVC decision, KEV entry, or POC was provided, so exploitation-in-the-wild probability cannot be quantified from the input; the absence of these signals means the urgency rests on the CVSS profile and the 'Authentication Bypass' tag rather than on confirmed exploitation. The lack of availability impact (A:N) is consistent with a data-access/authentication-bypass flaw rather than a denial-of-service. Because Oracle CPU advisories batch many issues and Oracle does not publish EPSS/KEV data itself, treat missing exploitation signals as unknown, not as low risk.

Exploit ScenarioDerived

An attacker who can reach an Oracle HTTP Server HTTPS endpoint over the network sends a crafted HTTPS request that abuses the mod_ssl authentication-bypass weakness, causing the server to treat the request as authorized without valid credentials. The attacker then reads, alters, or deletes data accessible to the server. No public POC was identified at time of analysis, but the low attack complexity and lack of required authentication make weaponization straightforward if exploit details emerge.

AnalysisAIv1 – Jul 22, 2026

Unauthenticated compromise of Oracle HTTP Server 12.2.1.4.0 and 14.1.2.0.0 (a Fusion Middleware component) is possible over the network via HTTP against the mod_ssl module, letting a remote attacker read, create, delete or modify all server-accessible data. Rated CVSS 3.1 9.1 with high confidentiality and integrity impact but no availability impact, and tagged as an authentication bypass. No public exploit identified at time of analysis and it is not listed in CISA KEV, but the trivial exploitability (AV:N/AC:L/PR:N/UI:N) makes it a high-priority patch.

RemediationAI

Apply the fixes delivered in the Oracle July 2026 Critical Patch Update per the advisory at https://www.oracle.com/security-alerts/cpujul2026.html, which is the primary and vendor-authoritative remediation for both affected releases (12.2.1.4.0 and 14.1.2.0.0); an exact fixed build number was not included in the input, so identify the specific CPU patch for your OHS version from that advisory. Patch available per vendor advisory. As interim compensating controls until patching, restrict network reachability of the OHS HTTPS listeners to trusted networks via firewall or ACLs, place the server behind a hardened reverse proxy or WAF that enforces authentication independently, and if client-certificate or mod_ssl-based access enforcement is used, audit and tighten those rules - noting that restricting listener exposure may break legitimate external clients and that a fronting proxy adds operational complexity and a new trust boundary. Because the flaw is an authentication bypass, do not rely on mod_ssl's own access controls as the mitigation.

Technical ContextAI · show details

Oracle HTTP Server (OHS) is Oracle's web tier built on the Apache HTTP Server codebase and shipped as part of Oracle Fusion Middleware, commonly fronting WebLogic and other middleware deployments. The affected component is mod_ssl, the module responsible for terminating TLS/SSL connections and, in some deployments, performing client-certificate based authentication and access control. The 'Authentication Bypass' tag combined with mod_ssl as the flaw location points to a weakness in how TLS/SSL identity or access enforcement is handled, allowing a request to be treated as authorized without valid credentials. No CWE was assigned in the source data, so the precise root-cause class (e.g., improper authentication or improper access control) cannot be confirmed from the input.

DescriptionCVE.org

Vulnerability in the Oracle HTTP Server product of Oracle Fusion Middleware (component: mod_ssl). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle HTTP Server. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle HTTP Server accessible data as well as unauthorized access to critical data or complete access to all Oracle HTTP Server accessible data. CVSS 3.1 Base Score 9.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N).

Executive ViewAI

Why It Matters

Oracle HTTP Server versions 12.2.1.4.0 and 14.1.2.0.0 contain a critical authentication bypass vulnerability in the mod_ssl module that allows unauthenticated remote attackers to read, modify, or delete server-accessible data. Organizations running these versions face immediate risk of data breach, integrity violation, and potential regulatory penalties. The trivial network exploitability (no credentials required) combined with the absence of a vendor patch creates urgent operational risk.

Business Impact: Severe
Compensating Controls

No vendor-released patch identified at time of analysis. Deploy interim defenses: (1) Network segmentation-restrict HTTP/HTTPS access to trusted internal IPs only; (2) Web Application Firewall-enable rules to detect mod_ssl exploitation patterns if signatures exist; (3) Disable mod_ssl-if not operationally required, disable the module to eliminate attack surface; (4) Backend authentication-enforce strong authentication on all data sources and applications behind the HTTP Server; (5) Enhanced logging-capture detailed HTTP request logs and mod_ssl activity to detect unauthorized access attempts; (6) Access restrictions-implement role-based controls to limit what data can be accessed or modified through the HTTP Server.
