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: 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

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), CVSS vector, 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

Until an official patch is released by AMTT, European hotels should implement the following mitigations: 1) Deploy web application firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the uid parameter in /user/portal/get_firstdate.php. 2) Restrict external access to the broadband operation system interface by implementing network segmentation and VPN access controls, limiting exposure to trusted personnel only. 3) Conduct thorough input validation and sanitization on all user-supplied parameters at the network gateway or proxy level if possible. 4) Monitor logs for unusual database query patterns or repeated access attempts to the vulnerable endpoint. 5) Perform regular security assessments and penetration tests focusing on this system to identify exploitation attempts. 6) Engage with AMTT for updates and consider alternative broadband management solutions if the vendor remains unresponsive. 7) Educate IT staff on this vulnerability and ensure incident response plans include steps for SQL injection attacks.

Description

A flaw has been found in AMTT Hotel Broadband Operation System 1.0. The impacted element is an unknown function of the file /user/portal/get_firstdate.php. Executing manipulation of the argument uid can lead to sql injection. It is possible to launch the attack remotely. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

For European organizations, particularly hotels and hospitality providers using the AMTT Hotel Broadband Operation System, this vulnerability poses a risk to the confidentiality and integrity of guest and operational data. Exploitation could lead to unauthorized access to sensitive customer information, manipulation of billing or network access records, and potential disruption of broadband services offered to guests. This could result in reputational damage, regulatory non-compliance (e.g., GDPR violations due to data breaches), and financial losses. Since the vulnerability can be exploited remotely without authentication, attackers could target hotels from anywhere, increasing the attack surface. The impact is heightened in countries with large tourism sectors and many hotels using this system. Additionally, compromised hotel broadband systems could be leveraged as pivot points for broader network intrusions within hotel IT infrastructure.

Summary

CVE-2025-13123 is a SQL injection vulnerability identified in AMTT Hotel Broadband Operation System version 1.0, specifically in the /user/portal/get_firstdate.php endpoint. The vulnerability arises from improper sanitization of the 'uid' parameter, allowing an attacker to inject malicious SQL queries. This injection flaw permits remote exploitation without requiring authentication or user interaction, increasing its risk profile. The vulnerability has a CVSS 4.0 base score of 5.3, reflecting medium severity due to limited impact on confidentiality, integrity, and availability and the requirement of low privileges (PR:L). The vendor was notified but has not issued any patches or advisories, and while a proof-of-concept exploit has been published, no active exploitation has been observed in the wild. Exploiting this vulnerability could enable attackers to extract sensitive information, modify database contents, or disrupt broadband operation services within hotel environments. Given the nature of the product—hotel broadband management systems—successful exploitation could compromise guest data, billing information, or network access controls. The lack of vendor response and patch availability increases the urgency for organizations to implement compensating controls. This vulnerability highlights the critical need for secure coding practices, especially input validation and parameterized queries, in web-facing hotel management systems.
