Exploitation Conditions

The CVSS vector PR:N/AV:N/AC:L/UI:N indicates no special conditions are required - exploitation is feasible against any network-accessible Apache OFBiz instance running a version prior to 24.09.06 without authentication or user interaction. The specific endpoint or feature containing the authentication bypass is not identified in the available advisory text, which limits precise pre-screening. Limiting factors include: impact is confined to partial confidentiality (C:L) with no integrity or availability consequence per CVSS, meaning attackers cannot modify data or disrupt availability through this vector alone; the application must be reachable over the network (internet-exposed or accessible from an attacker-controlled network segment); and no exploitation tooling has been publicly released, keeping realistic threat levels low at time of analysis.

Impact

The CVSS 3.1 score of 5.3 (Medium) with vector AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N quantifies the impact as limited to confidentiality (C:L) with no integrity or availability consequence - a constrained but real information-disclosure risk. EPSS at 0.02% (6th percentile) indicates very low current exploitation probability in the wild, suggesting the vulnerability has not attracted broad attacker tooling. No CISA KEV listing is present, and no public proof-of-concept has been identified. The SSVC assessment introduces a notable nuance: the attack is flagged as automatable despite its low EPSS, meaning automated scanners could probe at scale, and the partial technical impact aligns with CVSS C:L. The overall picture is a moderate-priority vulnerability - real and remotely exploitable without authentication, but constrained impact and no confirmed exploitation lower the urgency relative to integrity- or RCE-class flaws. Organizations running internet-exposed OFBiz instances should treat this as a timely patch rather than an emergency response.

Exploit ScenarioDerived

An unauthenticated remote attacker targets an internet-facing Apache OFBiz deployment running any version before 24.09.06, sending a specially crafted HTTP request that bypasses the application's authentication enforcement on a vulnerable endpoint. The attacker obtains read access to information that would normally require valid credentials, such as partial application data or configuration details. No public proof-of-concept has been identified at time of analysis, though SSVC confirms the attack path is automatable, making mass-scanning a realistic delivery mechanism.

AnalysisAIv1 – Jul 23, 2026

Improper authentication in Apache OFBiz before version 24.09.06 permits unauthenticated remote attackers to bypass authentication controls and access limited confidential information without valid credentials. The flaw (CWE-287) is exploitable over the network with no privilege or user interaction requirements, affecting all OFBiz deployments on unpatched versions. No public exploit has been identified at time of analysis, and EPSS rates exploitation probability at 0.02%; however, SSVC marks the attack path as automatable, making it a viable candidate for opportunistic scanning campaigns.

RemediationAI

Vendor-released patch: upgrade Apache OFBiz to version 24.09.06 as recommended by the Apache Software Foundation advisory at https://lists.apache.org/thread/3wgybgdvmbfvly24zm4sb4y53fc1pqcf. This is the primary and definitive fix. If immediate patching is not feasible, restrict network access to OFBiz administrative and application endpoints via WAF rules or firewall policies, limiting reachability to trusted internal networks or VPN-connected clients only - this mitigates the AV:N exploitation vector but requires careful scope definition to avoid breaking legitimate workflows. Additionally, review application-level access logs for unexpected unauthenticated request patterns to identify any prior exploitation attempts. No workarounds that address the root authentication logic are documented in available references.

Technical ContextAI · show details

Apache OFBiz is an open-source enterprise resource planning (ERP) framework maintained by the Apache Software Foundation, widely used for order management, accounting, inventory, and customer relationship management. The vulnerability is classified as CWE-287 (Improper Authentication), indicating that one or more authentication enforcement points in the application fail to adequately verify the identity of a requesting party, potentially allowing access to protected resources without valid credentials. The CPE string cpe:2.3:a:apache_software_foundation:apache_ofbiz:*:*:*:*:*:*:*:* covers all versions of the product in the affected range (any version prior to 24.09.06). The CVSS base vector AV:N/AC:L/PR:N/UI:N confirms the flaw resides in a network-exposed code path exercisable at low complexity with no prerequisites, consistent with an authentication-bypass class of defect in a web-facing endpoint.
