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 20 Jun 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 2026-10-26.

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

1. Immediate mitigation should include implementing strict input validation and output encoding on the Title and Description fields within /admin/manage-notices.php to neutralize malicious scripts. 2. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in the browser context. 3. Restrict access to the notice board administrative interface to trusted IP ranges or via VPN to reduce exposure. 4. Monitor web server logs for suspicious input patterns targeting the affected parameters. 5. If possible, upgrade to a patched or newer version of the PHPGurukul Notice Board System once available. 6. As a temporary workaround, disable the Add Notice functionality or restrict it to a minimal set of trusted users. 7. Educate administrative users about the risks of clicking on suspicious links or interacting with untrusted content within the notice board system. 8. Conduct regular security assessments and penetration tests focusing on web application vulnerabilities to detect similar issues proactively.

Description

A vulnerability, which was classified as problematic, has been found in PHPGurukul Notice Board System 1.0. This issue affects some unknown processing of the file /admin/manage-notices.php of the component Add Notice. The manipulation of the argument Title/Description leads to cross site scripting. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used.

Impact

For European organizations using PHPGurukul Notice Board System 1.0, this vulnerability could lead to unauthorized script execution within the administrative interface, potentially allowing attackers to hijack admin sessions, steal credentials, or perform actions on behalf of legitimate users. This could result in unauthorized disclosure of sensitive internal communications, manipulation of notices leading to misinformation, or use of the compromised system as a pivot point for further attacks within the corporate network. While the impact on availability is negligible, the integrity and confidentiality of internal data could be compromised. Organizations in sectors with stringent data protection requirements, such as finance, healthcare, and government, could face compliance risks and reputational damage if exploited. The medium severity score reflects that while the vulnerability is not critical, it still poses a meaningful risk if left unaddressed, especially in environments where the notice board system is integrated with other internal tools or contains sensitive information.
