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: 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

Detectable: no evidence on record.

Exploited in the wildExploited: no evidence on record.

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 restrict access to the /admin/add_account.php endpoint to trusted administrators only, using network segmentation and strong access controls. 2. Implement input validation and parameterized queries or prepared statements in the affected code to prevent SQL injection. 3. Monitor logs for suspicious SQL query patterns or unusual administrative activity indicative of exploitation attempts. 4. If vendor patches become available, apply them promptly. 5. Employ Web Application Firewalls (WAFs) with rules designed to detect and block SQL injection payloads targeting the vulnerable parameter. 6. Conduct a thorough security review of all input handling in the application to identify and remediate similar vulnerabilities. 7. Educate administrators on the risks of elevated privileges and enforce the principle of least privilege to limit potential damage. 8. Regularly back up databases and test restoration procedures to mitigate impact from data corruption or deletion.

Description

A security flaw has been discovered in code-projects Simple Online Hotel Reservation System 2.0. This affects an unknown function of the file /admin/add_account.php. The manipulation of the argument Name results in sql injection. The attack may be performed from remote. The exploit has been released to the public and may be used for attacks.

Impact

The SQL injection vulnerability allows attackers with elevated privileges to execute arbitrary SQL commands on the backend database of the Simple Online Hotel Reservation System. This can lead to unauthorized access to sensitive customer data, modification or deletion of records, and potential disruption of hotel reservation services. The partial compromise of confidentiality and integrity could result in leakage of personally identifiable information (PII), financial data, or booking details, impacting customer trust and regulatory compliance. Availability impacts, though low, could manifest as denial of service or corrupted data affecting operational continuity. Organizations relying on this software for managing hotel bookings and customer accounts face risks of reputational damage, financial loss, and legal consequences if exploited. The public availability of an exploit increases the likelihood of opportunistic attacks, especially in environments where patching is delayed or administrative controls are weak.

Summary

CVE-2025-12594 identifies a SQL injection vulnerability in the Simple Online Hotel Reservation System version 2.0 developed by code-projects. The vulnerability exists in the /admin/add_account.php file, where the 'Name' parameter is improperly sanitized before being incorporated into SQL queries. This allows a remote attacker to inject crafted SQL commands that can manipulate the backend database. The attack vector is network accessible (AV:N), requires low attack complexity (AC:L), and does not require user interaction (UI:N). However, it requires high privileges (PR:H), indicating that the attacker must have some elevated access, possibly an authenticated admin session. The vulnerability impacts confidentiality, integrity, and availability at a low level (VC:L, VI:L, VA:L), suggesting partial data exposure or modification and potential disruption. No scope change occurs (S:N), meaning the impact is confined to the vulnerable component. Although no known exploits are active in the wild, a public exploit has been released, increasing the risk of exploitation. The vulnerability was published on November 2, 2025, and has a CVSS 4.0 base score of 5.1, categorized as medium severity. The lack of available patches or vendor advisories at this time necessitates immediate attention from users of this software to implement mitigations or workarounds.
