MITRE ATT&CK
2 techniques across 2 tactics: Execution, Initial Access The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | No special conditions beyond running an affected build - remote unauthenticated exploitation against default configurations of Apache OFBiz 24.09 prior to 24.09.08. The attack requires only a well-formed multipart upload held in flight (no malformed/incomplete body needed) plus an anonymous JSON request to override mainDecoratorLocation; the widget XML is read from the live process file descriptor while streaming, so the attacker need not persist any file to disk. The description further establishes the flaw is reachable via the public, explicitly unauthenticated /sfa/control/editPortalPageColumnWidth route, so it is not limited to the login-failure rendering path. The only real limiting factor is version: deployments on 24.09.08 or outside the 24.09 branch range are not stated to be affected. |
| Impact | All severity signals align toward high priority. The provided CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, base 9.8) describes remote, unauthenticated, low-complexity code execution with full confidentiality/integrity/availability impact, and the vuln.today decision label is act_now - so urgent remediation is indicated. The description reinforces rather than contradicts the vector: it documents a public, explicitly unauthenticated route (/sfa/control/editPortalPageColumnWidth) that returns command output directly in an HTTP 200 response, confirming the network/no-privilege metrics are realistic rather than theoretical. Two signals are MISSING from the input and should be noted explicitly: no EPSS exploitation-probability score is provided, and there is no CISA KEV entry, so active in-the-wild exploitation is NOT confirmed. No field in the input states 'POC: Publicly available (confirmed)'; the references are vendor/mailing-list advisories (a detailed oss-security technical write-up), not verified working exploit code. Net assessment: this is a genuine high-priority RCE on its merits (unauthenticated network RCE with a vendor fix available and an act_now label), not a high-CVSS-but-low-real-risk case, but the real-world exploitation rate cannot be quantified because EPSS and KEV data are absent. |
| Exploit ScenarioDerived | A remote, unauthenticated attacker sends a well-formed multipart upload containing crafted widget XML and keeps the connection in flight, then issues an anonymous JSON request that overrides mainDecoratorLocation so OFBiz loads the staged XML from the live upload file descriptor and evaluates an unsandboxed Groovy expression, yielding code execution on the server. Validation shows the same flaw is reachable through the public /sfa/control/editPortalPageColumnWidth route, which returns command output directly in an HTTP 200 response. No verified public exploit code is listed in the input, but a detailed technical advisory describing the chain exists on oss-security. |

Alert meAnalysisAIv2 – Nov 05, 2026
Remote unauthenticated code execution in Apache OFBiz 24.09 before 24.09.08 allows an attacker to execute arbitrary commands on the server by staging crafted widget XML in a multipart upload that is held in flight and overriding mainDecoratorLocation through an anonymous JSON request. The payload is loaded through OFBiz's live screen descriptor mechanism and an unsandboxed Groovy expression is evaluated during rendering; the same flaw is also reachable through the public /sfa/control/editPortalPageColumnWidth route, which can return command output in an HTTP 200 response. No public exploit is identified at time of analysis, and the vendor-released fix is 24.09.08.
Earlier versions of this analysis (1)
Unauthenticated remote code execution in Apache OFBiz versions prior to 24.09.08 is reachable through injection into a login-page widget that is processed before authentication, allowing a remote attacker who can reach the login page to execute arbitrary code with the application's privileges. The flaw is one of more than 40 issues fixed together in the 24.09.08 batch advisory; no public exploit was identified at time of analysis, and the specific vulnerable widget, parameter, and component are not named in the disclosure. Because the assessed vector is CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, it should be treated as a high-impact pre-authentication RCE until scoping details are available.
RemediationAI
Vendor-released patch: upgrade Apache OFBiz to 24.09.08, which the vendor states fixes this issue. Apply the upgrade to all affected 24.09 deployments; the available references do not document a vendor-supported workaround, so no alternative control is confirmed as complete. Advisory links: https://ofbiz.apache.org/ and https://seclists.org/oss-sec/2026/q4/516.

Technical ContextAI · show details
Apache OFBiz is a Java-based enterprise resource planning and e-commerce framework that renders screens from XML widget descriptors. The root cause is CWE-94 improper control of code generation: attacker-controlled widget XML can influence mainDecoratorLocation, be retrieved through the live screen descriptor mechanism from a streaming upload's process file descriptor rather than from a file persisted to disk, and lead to evaluation of an unsandboxed Groovy expression while the authentication-failure page is rendered. The CVSS vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H confirms network reachability with no privileges or user interaction, and the affected range is 24.09 before 24.09.08 on all platforms. The alternate /sfa/control/editPortalPageColumnWidth route is explicitly unauthenticated and can return command output directly, so exploitation is not limited to the login-failure rendering path; a well-formed multipart request held in flight is sufficient.

Attack Technique
Code injection occurs when an application accepts user input and passes it directly into a language interpreter or evaluator without proper sanitization.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
