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: 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: None: There is no loss of integrity within 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.

Exploitation evidence

Disclosed: evidence found.
CVE published 31 May 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

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 26 Oct 2026.

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 or the CVSS exploit maturity 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 audit their use of Yifang CMS and identify any installations running affected versions (2.0.0 to 2.0.2). Since no official patches are currently available, mitigation should focus on restricting access to the Admin Panel and the /api/File/downloadFile endpoint to trusted administrators only, ideally via network segmentation and firewall rules. Implement strict access controls and monitor for unusual file access patterns or attempts to exploit path traversal. Employ web application firewalls (WAFs) with custom rules to detect and block path traversal payloads targeting the 'File' parameter. Additionally, review and harden CMS configuration to minimize sensitive file exposure and ensure logging is enabled for audit trails. Organizations should engage with Yifang CMS vendors for updates or patches and plan for timely application once released. Finally, conduct regular security assessments and penetration testing to detect any exploitation attempts.

Description

A vulnerability, which was classified as problematic, was found in Yifang CMS up to 2.0.2. Affected is the function downloadFile of the file /api/File/downloadFile of the component Admin Panel. The manipulation of the argument File leads to path traversal. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used.

Impact

For European organizations using Yifang CMS versions 2.0.0 through 2.0.2, this vulnerability poses a moderate risk primarily related to unauthorized information disclosure. Attackers with elevated privileges could exploit the path traversal flaw to access sensitive configuration files, credentials, or other critical data stored on the CMS server. This could lead to further compromise or lateral movement within the network. While the vulnerability does not directly allow remote code execution or denial of service, the exposure of sensitive files can undermine the confidentiality and integrity of organizational data. European organizations in sectors such as government, finance, healthcare, and critical infrastructure that rely on Yifang CMS for content management may face increased risk, especially if internal access controls are weak or if attackers can escalate privileges to the required level. The lack of public exploits reduces immediate risk, but the public disclosure means attackers could develop exploits, increasing the threat over time.
