Availability: None

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: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
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.

Exploitation evidence

Disclosed: evidence found.
CVE published 26 Jan 2024
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 2026-10-26.

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 immediately assess their use of Cups Easy (Purchase & Inventory) version 1.0 and implement the following specific mitigations: 1) Apply any vendor-provided patches or updates as soon as they become available; since no patches are currently linked, monitor vendor channels closely. 2) Implement Web Application Firewall (WAF) rules to detect and block malicious payloads targeting the 'stateid' parameter, focusing on script injection patterns. 3) Conduct user awareness training emphasizing the risks of clicking on unsolicited or suspicious URLs, especially those related to internal business applications. 4) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts within the application context. 5) Review and enhance input validation and output encoding practices in the application codebase if custom modifications exist, ensuring all user inputs are properly sanitized. 6) Monitor logs for unusual access patterns or repeated attempts to access the vulnerable endpoint with suspicious parameters. 7) Consider isolating or restricting access to the application to trusted networks or VPN users to reduce exposure to external attackers.

Description

A vulnerability has been reported in Cups Easy (Purchase & Inventory), version 1.0, whereby user-controlled inputs are not sufficiently encoded, resulting in a Cross-Site Scripting (XSS) vulnerability via /cupseasylive/statecreate.php, in the stateid parameter. Exploitation of this vulnerability could allow a remote attacker to send a specially crafted URL to an authenticated user and steal their session cookie credentials.

Impact

For European organizations using Cups Easy (Purchase & Inventory) version 1.0, this vulnerability poses a significant risk to the confidentiality of sensitive business data and user credentials. Successful exploitation could allow attackers to hijack authenticated sessions, leading to unauthorized access to purchase and inventory management data. This could disrupt business operations, cause financial loss, and expose sensitive supplier or customer information. Given the nature of the software, attackers might also manipulate inventory or purchase records indirectly by gaining unauthorized access, although the integrity impact is rated low. The lack of availability impact means the service remains operational, but the breach of confidentiality alone can have serious regulatory and reputational consequences, especially under GDPR requirements for protecting personal and business data. The requirement for user interaction (clicking a malicious link) means phishing or social engineering campaigns could be used to exploit this vulnerability, which is a common attack vector in Europe.

Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Implementation · Architecture and Design
Understand the context in which your data will be used and the encoding that will be expected. This is especially important when transmitting data between different components, or when generating outputs that can contain multiple encodings at the same time, such as web pages or multi-part mail messages.
Architecture and Design · Implementation · Attack Surface Reduction
Understand all the potential areas where untrusted inputs can enter your software: parameters or arguments, cookies, anything read from the network, environment variables, reverse DNS lookups, query results, request headers, URL components, e-mail, files, filenames, databases, and any external systems that provide…
