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: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
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 8 Oct 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

To mitigate CVE-2025-11433, organizations should first verify if they are running itsourcecode Leave Management System version 1.0 and restrict access to the vulnerable endpoint where possible. Input validation and output encoding should be enforced at the application level to sanitize user-supplied data, preventing script injection. Administrators should educate users about phishing risks and avoid clicking on suspicious links. Monitoring web server logs for unusual query parameters or repeated access attempts to the vulnerable function can help detect exploitation attempts. Where feasible, isolating the Leave Management System from direct internet exposure or requiring VPN access can reduce attack surface. Organizations should also engage with the vendor for updates or patches and plan for prompt application once available. Finally, conducting regular security assessments and penetration testing can help identify similar vulnerabilities proactively.

Description

A security flaw has been discovered in itsourcecode Leave Management System 1.0. This impacts the function redirect of the file /module/employee/controller.php?action=reset of the component Query Parameter Handler. Performing a manipulation of the argument ID results in cross site scripting. It is possible to initiate the attack remotely. The exploit has been released to the public and may be used for attacks.

Impact

The impact of CVE-2025-11433 on organizations is primarily related to the compromise of user sessions and potential unauthorized actions within the Leave Management System. Successful exploitation can lead to theft of sensitive employee data, manipulation of leave records, or unauthorized access to internal HR functions. This can result in operational disruption, privacy violations, and reputational damage. Since the vulnerability allows remote exploitation without authentication, attackers can target employees via phishing or social engineering to deliver malicious URLs. The medium severity score indicates that while the vulnerability is not critical, it poses a tangible risk especially in environments where the Leave Management System integrates with other internal systems or contains sensitive personnel information. Organizations with large employee bases or regulatory requirements for data protection may face compliance risks if exploited. Additionally, the presence of a public exploit increases the likelihood of opportunistic attacks, making timely mitigation essential.
