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: High: The attacker requires privileges that provide significant (e.g., administrative) control over the vulnerable system allowing full access to the vulnerable system’s settings and files.
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

Detectable: no evidence on record.
No public nuclei template indexed

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

1. Immediate mitigation should include implementing strict input validation and output encoding on all user-controllable inputs within the /cms/webpage/ Pages Image Handler component to prevent script injection. 2. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 3. Monitor web server logs for suspicious requests targeting the vulnerable endpoints to detect potential exploitation attempts. 4. Isolate or restrict access to the affected component if possible, limiting exposure. 5. Educate users and administrators about the risk of phishing or social engineering attacks leveraging this vulnerability. 6. Engage with oitcode for official patches or updates and plan for prompt deployment once available. 7. Consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block XSS payloads targeting the affected paths. 8. Regularly review and update security policies to include this vulnerability and ensure compliance with data protection laws.

Description

A security flaw has been discovered in oitcode samarium up to 0.9.6. This vulnerability affects unknown code of the file /cms/webpage/ of the component Pages Image Handler. The manipulation results in cross site scripting. The attack may be performed from a remote location. The exploit has been released to the public and may be exploited.

Impact

For European organizations using oitcode samarium, this XSS vulnerability poses a moderate risk. Successful exploitation could lead to session hijacking, theft of sensitive user data, or unauthorized actions performed on behalf of users, undermining trust and potentially violating data protection regulations such as GDPR. Organizations operating public-facing web portals or CMS platforms based on samarium are particularly vulnerable, as attackers can exploit this remotely. The impact on confidentiality and integrity is notable, though availability is not directly affected. Given the public availability of an exploit, attackers may attempt phishing campaigns or targeted attacks against European entities relying on this software. This could result in reputational damage, regulatory penalties, and financial losses. The medium severity rating suggests the threat is significant but not critical, emphasizing the need for timely mitigation to prevent exploitation.

Summary

CVE-2025-9416 is a cross-site scripting (XSS) vulnerability identified in the oitcode samarium product, specifically affecting versions 0.9.0 through 0.9.6. The vulnerability resides in an unspecified portion of the /cms/webpage/ directory within the Pages Image Handler component. This flaw allows an attacker to inject malicious scripts that execute in the context of a victim's browser when they visit a compromised or crafted webpage. The vulnerability can be exploited remotely without requiring authentication, although user interaction is necessary for the malicious script to execute (e.g., the victim must visit the affected page). The CVSS 4.0 base score is 4.8, indicating a medium severity level. The vector details show that the attack vector is network-based (AV:N), with low attack complexity (AC:L), no privileges required (PR:H indicates high privileges required, but this conflicts with the description; likely a data inconsistency), and user interaction is required (UI:P). The vulnerability impacts the confidentiality and integrity of the victim's session or data by enabling script execution, potentially leading to session hijacking, defacement, or redirection to malicious sites. No known exploits are currently observed in the wild, but a public exploit has been released, increasing the risk of exploitation. No patches or fixes have been linked yet, so affected users must rely on mitigation strategies until an official update is available.
