Threat metrics

Exploit Maturity: POC

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the Vulnerable System.
Vulnerable system integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact to the Vulnerable System.
Vulnerable system availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the Vulnerable System are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

Exploitation evidence

Disclosed: evidence found.
CVE published 19 Jul 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-25.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

European organizations should immediately assess their deployment of Jinher OA 1.1 and prioritize upgrading to a patched or newer version if available. In the absence of an official patch, organizations should implement the following mitigations: 1) Disable or restrict XML external entity processing in the XmlHttp.aspx component or the underlying XML parser configuration to prevent external entity resolution. 2) Employ web application firewalls (WAFs) with custom rules to detect and block XML payloads containing external entity declarations or suspicious patterns targeting XmlHttp.aspx. 3) Conduct network segmentation to limit the exposure of Jinher OA servers, restricting inbound traffic to trusted sources only. 4) Monitor logs for unusual XML requests or error messages indicative of exploitation attempts. 5) Implement strict input validation and sanitization on XML inputs where possible. 6) Engage with Jinher support or vendor channels to obtain official patches or guidance. 7) Educate IT and security teams about the vulnerability and ensure incident response plans are updated to address potential exploitation scenarios. These measures, combined, reduce the risk of exploitation while maintaining operational continuity.

Description

A vulnerability was found in Jinher OA 1.1. It has been rated as problematic. This issue affects some unknown processing of the file XmlHttp.aspx. The manipulation leads to xml external entity reference. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used.

Impact

For European organizations using Jinher OA 1.1, this vulnerability poses a significant risk, especially for entities relying on this software for internal communications and document management. Exploitation could lead to unauthorized disclosure of sensitive internal files, potentially exposing confidential business information or personal data protected under GDPR. Additionally, attackers could leverage the vulnerability to perform SSRF attacks, potentially pivoting into internal networks or accessing restricted resources, increasing the risk of broader compromise. The medium severity rating suggests that while the vulnerability may not directly cause system-wide outages, the confidentiality and integrity of critical data could be compromised. This is particularly concerning for sectors such as government, finance, healthcare, and critical infrastructure in Europe, where data protection and operational continuity are paramount. The remote and unauthenticated nature of the exploit increases the attack surface, making it accessible to a wide range of threat actors, including cybercriminals and state-sponsored groups. The lack of known exploits in the wild currently provides a window for mitigation, but the public disclosure means that this window may close rapidly.
