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: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
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 19 Nov 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 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

1. Immediately implement input validation and sanitization for the eventSubject parameter to prevent malicious SQL code injection. 2. Employ parameterized queries or prepared statements in the EventStore.php file to eliminate direct concatenation of user input into SQL commands. 3. Restrict network access to the HRMS application, limiting exposure to trusted internal networks or VPNs where possible. 4. Monitor database logs and application logs for unusual query patterns or repeated failed attempts indicative of SQL injection attempts. 5. Conduct a thorough code review of the HRMS application to identify and remediate other potential injection points. 6. If vendor patches become available, prioritize their deployment. 7. Implement web application firewalls (WAF) with SQL injection detection rules tailored to the HRMS environment. 8. Educate system administrators and security teams on the vulnerability and signs of exploitation to enable rapid incident response. 9. Consider isolating the HRMS system or deploying it within segmented network zones to limit lateral movement in case of compromise. 10. Regularly back up HRMS data and verify backup integrity to enable recovery from potential data tampering or loss.

Description

A weakness has been identified in itsourcecode Human Resource Management System 1.0. This issue affects some unknown processing of the file /src/store/EventStore.php. This manipulation of the argument eventSubject causes sql injection. The attack can be initiated remotely. The exploit has been made available to the public and could be exploited.

Impact

For European organizations using itsourcecode Human Resource Management System 1.0, this vulnerability could lead to unauthorized access to sensitive employee and organizational data, including personal identifiable information (PII), payroll, and HR records. Exploitation could result in data breaches, regulatory non-compliance (e.g., GDPR violations), reputational damage, and potential operational disruptions if data integrity or availability is compromised. Attackers could manipulate or exfiltrate data, potentially leading to insider threat scenarios or fraud. The medium severity indicates a significant risk that could escalate if combined with other vulnerabilities or insider threats. Given the remote and unauthenticated nature of the exploit, attackers can target vulnerable systems over the internet, increasing exposure. European organizations in sectors with strict data protection requirements, such as finance, healthcare, and government, may face heightened consequences. The lack of patches increases the urgency for interim mitigations to prevent exploitation.
