A vulnerability has been found in code-projects Local Storage Todo App 1.0 and classified as problematic. This vulnerability affects unknown code of the file /js-todo-app/index.html. The manipulation of the argument Add leads to cross site scripting. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used.
The severity level of this vulnerability is medium, with a CVSS score of 5.1, indicating that it poses a moderate risk to organizations. This cross site scripting vulnerability can allow attackers to execute scripts in the context of a user's session, potentially leading to data theft or session hijacking.
Given the exploitability of this vulnerability, organizations should prioritize patching immediately. The remote nature of the attack vector increases the urgency for organizations to implement protective measures without delay.
As of now, there are no known public exploits associated with this vulnerability, and it is not listed in the Known Exploited Vulnerabilities (KEV) catalog. However, the potential for remote exploitation remains a concern.
Vulnerability Details
The vulnerability in question allows for cross site scripting (CWE-79) and reflects potential flaws in input validation. The affected product is the local_storage_todo_app version 1.0, published on January 5, 2025, with the last modification occurring on January 10, 2025.
The CVSS score of 5.1 indicates a medium severity, with an attack vector of NETWORK, low complexity of attack, and high privileges required. The integrity impact is classified as low, while confidentiality and availability impacts are none.
Technical Analysis
The root cause of this vulnerability stems from improper validation of user input, allowing for the manipulation of the Add argument in the application. The attack vector is over the network, with a low complexity for exploitation, requiring high privileges, and no user interaction needed.
The confidentiality impact is none, while the integrity impact is low, meaning that an attacker could potentially alter data. Availability impact is classified as none, indicating that the service remains operational even if the vulnerability is exploited.
Risk & Impact Analysis
Risk to organizations includes potential data theft, unauthorized access, and the ability for attackers to execute arbitrary scripts in the context of a user's session. This could allow for extensive exploitation, especially if sensitive information is accessible through the affected application.
The blast radius of this vulnerability could extend to any user of the Local Storage Todo App, with potential for significant impact if exploited effectively. Organizations should assess their exposure and address this vulnerability based on the medium severity and the potential for exploitation.
