CVE-2026-108057 in ALO Suite
Summary
by MITRE • 11/03/2026
A stored Cross-Site Scripting (XSS) vulnerability in Alosuite that affects the delivery note functionality. Insufficient sanitization and encoding of the specified fields allow JavaScript to be stored, which executes in other users’ browsers when they view the affected records. Exploitation requires authenticated access to the affected functionality. The code can alter the displayed content and perform actions within the context of the victim’s session. The list of features, parameters, and endpoints is as follows:
CVE-2026-108057: Nombre in ‘/PlantillasPdf/Edit/1273129’;

The vulnerability identified under CVE-2026-108057 represents a critical security flaw within the Alosuite enterprise resource planning software, specifically targeting its delivery note management subsystem. This issue is classified as a Stored Cross-Site Scripting (XSS) vulnerability, which poses a significant risk to organizational data integrity and user safety. The root cause lies in insufficient sanitization and encoding mechanisms applied to specific input fields during the creation or modification of PDF templates used for generating delivery notes. When an authenticated user submits malicious JavaScript code into these fields, such as the Nombre parameter within the /PlantillasPdf/Edit/1273129 endpoint, the application fails to properly escape special characters before storing the data in its backend database. Consequently, when other users subsequently view or generate documents based on this compromised template, the browser interprets the stored script as executable code rather than static content. This execution occurs within the security context of the victim’s active session, allowing the attacker to bypass same-origin policy restrictions and interact directly with the application's DOM elements.
From a technical perspective, this flaw aligns closely with CWE-79, which describes Improper Neutralization of Input During Web Page Generation commonly known as Cross-site Scripting. The specific nature of this vulnerability is persistent because the malicious payload resides on the server side rather than being transmitted solely via URL parameters or HTTP headers in transient requests. This persistence ensures that every user accessing the affected delivery note functionality becomes a potential victim, amplifying the blast radius significantly compared to reflected XSS attacks. The exploitation vector requires authenticated access, which limits the attack surface to internal users but increases the severity of the impact due to the trusted nature of these sessions. Attackers with valid credentials can inject scripts that perform actions such as stealing session cookies, capturing keystrokes, or performing unauthorized state-changing requests on behalf of the victim. This capability effectively allows for account takeover and further lateral movement within the network if combined with other vulnerabilities.
The operational impact of this vulnerability extends beyond simple defacement or alert boxes. Since Alosuite is often used in logistics and supply chain management environments where delivery notes are critical documentation, compromising these records can lead to severe business disruptions. An attacker could alter displayed content to mislead warehouse staff about shipment details, leading to logistical errors. More critically, the ability to perform actions within the victim’s session context means that sensitive data such as customer addresses, invoice amounts, and internal supplier contacts can be exfiltrated to an external server controlled by the attacker. This constitutes a direct violation of confidentiality requirements under standards like ISO/IEC 27001. Furthermore, if the application integrates with other systems via APIs or webhooks triggered by document generation, the malicious script could potentially propagate attacks to downstream services, expanding the attack chain significantly.
In terms of threat modeling and detection, this vulnerability maps directly to MITRE ATT&CK technique T1059.007, which refers to JavaScript Execution within a browser environment. The persistence mechanism aligns with T1189 Drive-by Compromise or more accurately T1204 User Execution if the victim is tricked into viewing specific records, though in this case it is more akin to data injection leading to automated execution upon access. Security operations teams should monitor for unusual patterns of JavaScript code being stored within database fields associated with document templates and look for anomalous outbound network traffic originating from web servers hosting Alosuite instances that may indicate exfiltration attempts via beaconing scripts embedded in the generated pages.
Mitigation strategies must address both immediate remediation and long-term architectural improvements. The primary fix involves implementing rigorous input validation and output encoding on all fields involved in PDF template generation, particularly those exposed through endpoints like /PlantillasPdf/Edit/. Developers should utilize context-aware encoding libraries that correctly escape HTML entities based on the specific location of the data within the DOM structure. Additionally, enabling Content Security Policy (CSP) headers can significantly mitigate the impact by restricting the sources from which scripts are allowed to execute, thereby preventing inline script execution even if injection occurs. For existing deployments, administrators should immediately audit all stored templates for malicious content and rotate credentials for any accounts that may have been used to inject payloads. Regular security code reviews focusing on data flow analysis will help identify similar sanitization gaps in other modules of the Alosuite platform before they can be exploited by adversaries seeking persistent access or data theft capabilities.
