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

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, 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: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
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 on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

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

European organizations should immediately audit their use of SSCMS and identify any instances of version 7.3.1. Until an official patch is released, organizations should implement strict access controls to limit the number of users with privileges sufficient to exploit this vulnerability. Network-level restrictions such as IP whitelisting or VPN-only access to the CMS management interfaces can reduce exposure. Web application firewalls (WAFs) should be configured to detect and block suspicious GET requests targeting /cms/templates/templatesAssetsEditor, especially those containing unusual query parameters or payloads. Monitoring and logging of access to this endpoint should be enhanced to detect potential exploitation attempts. Additionally, organizations should conduct internal penetration testing focused on this vulnerability to assess exposure. Once a patch or vendor advisory is available, prompt application of updates is essential. If patching is delayed, consider temporary disabling or restricting access to the vulnerable functionality if feasible. Finally, ensure that sensitive files are not unnecessarily stored in web-accessible directories and that file permissions follow the principle of least privilege.

Description

An arbitrary file read vulnerability in the ReadTextAsynchronous function of SSCMS v7.3.1 allows attackers to read arbitrary files via sending a crafted GET request to /cms/templates/templatesAssetsEditor.

Impact

For European organizations using SSCMS 7.3.1, this vulnerability poses a significant risk to confidentiality of sensitive information stored on CMS servers. Attackers could leverage this flaw to access configuration files, database credentials, or other sensitive documents, potentially enabling further compromise or data leakage. This could lead to exposure of personal data protected under GDPR, resulting in regulatory penalties and reputational damage. The integrity impact is low, so direct modification of files is unlikely, but the information disclosure alone can facilitate subsequent attacks such as privilege escalation or lateral movement. Availability is not affected, so service disruption is not expected. Organizations in sectors with high reliance on CMS platforms for public-facing websites, such as government, finance, healthcare, and media, are particularly at risk. The requirement for low privileges means insider threats or attackers who have gained limited access could exploit this vulnerability to escalate their information access. Given the lack of known exploits, proactive mitigation is critical to prevent exploitation once public exploit code emerges.
