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

CVE published 7 Oct 2025
Detectable: no evidence on record.
No public nuclei template indexed

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

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 audit all instances of SourceCodester Hotel and Lodge Management System version 1.0 to identify affected deployments. 2. Implement strict input validation and sanitization on the email parameter in /login.php, ensuring that only valid email formats are accepted. 3. Refactor database queries to use parameterized statements or prepared queries to eliminate SQL injection vectors. 4. Monitor database logs and application logs for unusual query patterns or repeated failed login attempts indicative of exploitation attempts. 5. Restrict database user permissions to the minimum necessary to limit the impact of any injection. 6. Deploy web application firewalls (WAFs) with rules specifically targeting SQL injection patterns on the affected endpoint. 7. Engage with the vendor or community to obtain or develop official patches and apply them promptly once available. 8. Conduct security awareness training for IT staff to recognize and respond to exploitation attempts. 9. Regularly back up critical data and verify restoration procedures to mitigate potential data loss from attacks.

Description

A security flaw has been discovered in SourceCodester Hotel and Lodge Management System 1.0. The affected element is an unknown function of the file /login.php. Performing manipulation of the argument email results in sql injection. The attack may be initiated remotely. The exploit has been released to the public and may be exploited.

Impact

For European organizations, exploitation of this SQL injection vulnerability could lead to unauthorized access to sensitive customer and business data, including personal identification, booking records, and payment information. This could result in data breaches, regulatory non-compliance (e.g., GDPR violations), reputational damage, and financial losses. Additionally, attackers might alter or delete critical operational data, disrupting hotel management services and causing availability issues. The hospitality sector in Europe is a high-value target due to its economic importance and the volume of personal data processed. Organizations using the affected software without proper mitigations are at increased risk of targeted attacks, potentially impacting customer trust and operational continuity.

Summary

CVE-2025-11397 identifies a SQL injection vulnerability in the SourceCodester Hotel and Lodge Management System version 1.0. The vulnerability exists in an unspecified function within the /login.php file, where the email parameter is improperly sanitized, allowing attackers to inject malicious SQL code. This injection flaw can be exploited remotely without authentication or user interaction, enabling attackers to manipulate backend database queries. Potential consequences include unauthorized retrieval, modification, or deletion of sensitive data stored in the database, such as user credentials, booking information, or payment details. The vulnerability has a CVSS 4.0 score of 6.9, reflecting a medium severity level due to its network attack vector, lack of required privileges, and no user interaction needed, but with limited impact on confidentiality, integrity, and availability. Although no confirmed exploits are currently active in the wild, the public release of exploit code increases the likelihood of attacks. The lack of available patches at the time of disclosure necessitates immediate interim mitigations. This vulnerability poses a significant risk to organizations relying on this software for managing hotel and lodge operations, especially those handling sensitive customer data.
