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.

Exploitation evidence

Disclosed: evidence found.
CVE published 5 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 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 or the CVSS exploit maturity 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

Immediate mitigation should include implementing web application firewall (WAF) rules to detect and block SQL injection patterns targeting the /forgot-password.php endpoint, especially filtering suspicious 'email' parameter inputs.
Organizations should audit their PHPGurukul Notice Board System installations to confirm the version in use; if version 1.0 is deployed, consider disabling the forgot-password functionality temporarily until a patch is available.
Employ input validation and parameterized queries or prepared statements in the application code to prevent SQL injection; if source code access is available, developers should remediate the vulnerable code promptly.
Monitor logs for unusual database query patterns or repeated failed password reset attempts that could indicate exploitation attempts.
Restrict database user permissions to the minimum necessary to limit the impact of a successful injection.
If feasible, isolate the affected system within the network and limit external access to reduce exposure.
Stay updated with vendor advisories for patches or official fixes and apply them immediately once released.

Description

A vulnerability was found in PHPGurukul Notice Board System 1.0 and classified as critical. Affected by this issue is some unknown functionality of the file /forgot-password.php. The manipulation of the argument email leads to sql injection. The attack may be launched 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 poses a risk of unauthorized database access, potentially exposing sensitive internal communications or user credentials. The SQL Injection could allow attackers to extract confidential information, alter notice board content, or disrupt availability by deleting or corrupting data. Given the system's typical use in educational or small organizational contexts, the impact may be more pronounced in institutions relying heavily on this software for internal announcements. The remote and unauthenticated nature of the exploit increases the risk of automated scanning and exploitation attempts. While the overall market penetration of this specific product in Europe is likely limited, organizations that have deployed it without timely updates or mitigations are vulnerable. The lack of a patch and public exploit availability means organizations must proactively mitigate the risk to prevent potential data breaches or service disruptions.
