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: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
User Interaction: Passive: Successful exploitation of this vulnerability requires limited interaction by the targeted user with the vulnerable system and the attacker’s payload. These interactions would be considered involuntary and do not require that the user actively subvert protections built into the vulnerable system.
Vulnerable system confidentiality: None: There is no loss of confidentiality within 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: None: There is no impact to availability within 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

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 implement the following specific measures: 1) Immediately restrict public access to the affected /x_cms_assemble_control/jaxrs/form endpoint using web application firewalls (WAFs) or reverse proxies to filter and block suspicious input patterns indicative of XSS payloads. 2) Employ content security policies (CSP) to limit the execution of unauthorized scripts in browsers accessing O2OA. 3) Conduct thorough input validation and output encoding on all user-supplied data within the Personal Profile Page component to prevent script injection. 4) Monitor logs for unusual requests targeting the vulnerable endpoint and implement alerting for potential exploitation attempts. 5) Educate users about phishing risks and suspicious links to reduce the likelihood of successful user interaction exploitation. 6) Plan and execute an upgrade to the fixed version of O2OA as soon as it is released by the vendor. 7) If immediate patching is not possible, consider temporary mitigation by disabling or limiting the vulnerable functionality until a patch is available.

Description

A vulnerability was found in O2OA up to 10.0-410. Affected by this issue is some unknown functionality of the file /x_cms_assemble_control/jaxrs/form of the component Personal Profile Page. The manipulation results in cross site scripting. The attack may be launched remotely. The exploit has been made public and could be used. The vendor replied in the GitHub issue (translated from simplified Chinese): "This issue will be fixed in the new version."

Impact

For European organizations using O2OA, this vulnerability poses a tangible risk to user data and system integrity. Since O2OA is a collaborative office automation platform, exploitation could lead to unauthorized access to personal profiles, leakage of sensitive information, and potential compromise of user sessions. This can disrupt business operations, damage reputation, and lead to compliance issues under regulations such as GDPR due to potential exposure of personal data. The remote exploitability without authentication increases the attack surface, especially for organizations with public-facing O2OA instances. The requirement for user interaction means phishing or social engineering campaigns could be used to trigger the exploit, targeting employees or partners. Although the CVSS score is medium, the presence of public exploit code elevates the urgency for mitigation. Organizations in sectors with high data sensitivity or regulatory scrutiny in Europe should prioritize addressing this vulnerability to avoid operational and legal consequences.

Summary

CVE-2025-9683 is a cross-site scripting (XSS) vulnerability identified in the O2OA platform, specifically affecting versions up to 10.0-410. The vulnerability resides in an unspecified functionality within the /x_cms_assemble_control/jaxrs/form endpoint of the Personal Profile Page component. This flaw allows an attacker to inject malicious scripts that can be executed in the context of a victim's browser session. The vulnerability can be exploited remotely without requiring authentication, although user interaction is necessary to trigger the malicious script (e.g., by visiting a crafted URL or interacting with a malicious form). The CVSS 4.0 base score is 5.1, indicating a medium severity level. The attack vector is network-based with low attack complexity and no privileges required, but user interaction is needed. The vulnerability impacts confidentiality and integrity to a limited extent, as it can lead to session hijacking, credential theft, or unauthorized actions performed on behalf of the user. Exploit details have been publicly disclosed, increasing the risk of exploitation, although no confirmed in-the-wild attacks have been reported yet.
