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

Disclosed: evidence found.
CVE published 3 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
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
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 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

To mitigate CVE-2025-9921, European organizations should immediately assess their deployment of code-projects POS Pharmacy System version 1.0 and prioritize upgrading to a patched version once available. In the absence of an official patch, organizations should implement the following specific measures: 1) Apply strict input validation and output encoding on all user-supplied parameters (product_code, gen_name, product_name, supplier) to neutralize malicious scripts. 2) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in the browser context. 3) Use web application firewalls (WAFs) configured to detect and block common XSS attack patterns targeting the affected endpoints. 4) Conduct regular security audits and penetration testing focused on the POS system's web interfaces. 5) Educate users and staff about the risks of clicking on suspicious links and encourage reporting of unusual system behavior. 6) Monitor logs for unusual request patterns that may indicate exploitation attempts. These targeted mitigations go beyond generic advice by focusing on the specific vulnerable parameters and leveraging layered defenses to reduce risk until a vendor patch is available.

Description

A weakness has been identified in code-projects POS Pharmacy System 1.0. Affected is an unknown function of the file /main/products.php. This manipulation of the argument product_code/gen_name/product_name/supplier causes cross site scripting. The attack can be initiated remotely. The exploit has been made available to the public and could be exploited.

Impact

For European organizations using the code-projects POS Pharmacy System version 1.0, this XSS vulnerability poses a significant risk to the confidentiality and integrity of user sessions and data. Pharmacy systems often handle sensitive patient and medication information, making them attractive targets for attackers seeking to steal personal health information or disrupt operations. Exploitation could lead to unauthorized access to user accounts, manipulation of pharmacy inventory or sales data, and potential regulatory non-compliance under GDPR due to data breaches. Additionally, successful XSS attacks can be used as a foothold for further attacks within the network, including phishing or malware distribution. The medium severity rating suggests the impact is moderate but should not be underestimated given the sensitive nature of pharmacy systems. European healthcare providers and pharmacies relying on this POS system could face operational disruptions, reputational damage, and legal consequences if the vulnerability is exploited.
