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: 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 8 Sep 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

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

Organizations should immediately identify all instances of ChanCMS version 3.3.0 and 3.3.1 in their environment. In the interim, implement web application firewall (WAF) rules to detect and block SQL injection patterns targeting the 'keyword' parameter in /cms/article/search requests. Conduct thorough input validation and sanitization on all user-supplied data, especially parameters used in database queries. Employ least privilege principles for database accounts used by ChanCMS to limit the impact of potential injection. Regularly monitor logs for suspicious activity related to SQL injection attempts. Additionally, consider isolating the CMS environment and restricting network access to trusted IPs where feasible. Finally, maintain an incident response plan to quickly address any exploitation attempts.

Description

A flaw has been found in yanyutao0402 ChanCMS up to 3.3.1. Affected by this issue is some unknown functionality of the file /cms/article/search. This manipulation of the argument keyword causes sql injection. The attack can be initiated remotely. The exploit has been published and may be used.

Impact

For European organizations using ChanCMS versions 3.3.0 or 3.3.1, this vulnerability poses a risk of unauthorized access to sensitive data stored in backend databases, including potentially personal data protected under GDPR. Exploitation could lead to data breaches, reputational damage, and regulatory penalties. Additionally, attackers could alter website content or disrupt service availability, impacting business continuity and customer trust. Since the vulnerability can be exploited remotely without user interaction, it increases the attack surface and risk of automated exploitation attempts. Organizations in sectors such as media, education, government, and e-commerce that rely on ChanCMS for content management are particularly at risk. The medium severity rating suggests a moderate but non-negligible threat that requires timely remediation to prevent escalation or chaining with other vulnerabilities.

Summary

CVE-2025-10105 is a medium severity SQL Injection vulnerability affecting yanyutao0402 ChanCMS versions up to 3.3.1, specifically in the /cms/article/search endpoint. The vulnerability arises from improper sanitization or validation of the 'keyword' parameter, allowing an attacker to inject malicious SQL code remotely without authentication or user interaction. This flaw enables an attacker to manipulate backend database queries, potentially leading to unauthorized data access, data modification, or disruption of service. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:L, indicating low privileges but some level of authentication), no user interaction (UI:N), and limited impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although no known exploits are currently observed in the wild, the public availability of proof-of-concept code increases the risk of exploitation. The vulnerability affects a CMS platform, which is often used to manage website content, making it a valuable target for attackers seeking to compromise web applications and extract sensitive information or deface websites.
