Exploitability
| CWE ID | Description |
|---|---|
| CWE-89 | The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data. |

AI Powered Q&A
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
The vulnerability allows unauthorized users, including unauthenticated guests, to perform SQL injection attacks that can lead to unauthorized access, modification, or denial of service affecting database information. This high-impact exposure of sensitive data and potential service disruption can lead to non-compliance with data protection regulations such as GDPR and HIPAA, which require strict controls on data confidentiality, integrity, and availability. [2]
Can you explain this vulnerability to me?
CVE-2025-65091 is a critical SQL injection vulnerability in the Calendar.JSONService component of the XWiki macro-fullcalendar package. Before version 2.4.5, any user with permission to view the Calendar.JSONService page, including guest users, could exploit this vulnerability by injecting malicious SQL code. This allows attackers to access unauthorized database information or cause denial-of-service (DoS) attacks. The vulnerability arises because the service previously used unsafe query construction methods that allowed direct injection of user input into database queries. [2]
How can this vulnerability impact me? :
This vulnerability can have severe impacts including unauthorized access to sensitive database information, modification of data, and disruption of service through denial-of-service (DoS) attacks. Since no authentication is required and the attack complexity is low, attackers can remotely exploit this vulnerability without user interaction, potentially compromising confidentiality, integrity, and availability of the affected system. [2]
What immediate steps should I take to mitigate this vulnerability?
To mitigate this vulnerability immediately, you should upgrade the XWiki macro-fullcalendar package to version 2.4.5 or later where the issue is patched. Alternatively, as a workaround, you can remove the Calendar.JSONService page, but note that this will break some functionalities. These steps prevent exploitation by eliminating the vulnerable SQL injection vector. [2]
