CVE-2025-32299 is a medium-severity vulnerability classified under CWE-497, which pertains to the Exposure of Sensitive System Information to an Unauthorized Control Sphere. This vulnerability affects Themovation's QuickCal application, specifically versions up to and including 1.0.15. The flaw allows an attacker with low privileges (PR:L) to remotely retrieve embedded sensitive data from the application without requiring user interaction (UI:N). The vulnerability is exploitable over the network (AV:N) with low attack complexity (AC:L), and it does not impact the integrity or availability of the system but compromises confidentiality to some extent (C:L, I:N, A:N). The vulnerability's CVSS 3.1 score is 4.3, indicating a medium risk level. No public exploits or patches are currently available, and the affected versions are not precisely enumerated beyond being up to 1.0.15. The vulnerability likely arises from improper handling or exposure of embedded sensitive information within the QuickCal application, which could include configuration details, credentials, or other confidential data embedded in the software. Attackers exploiting this vulnerability could gain unauthorized access to sensitive system information, potentially facilitating further attacks or reconnaissance activities.

For European organizations using Themovation QuickCal, this vulnerability poses a risk of unauthorized disclosure of sensitive embedded data. While the immediate impact is limited to confidentiality loss without direct integrity or availability consequences, the exposure of sensitive system information can aid attackers in crafting more targeted attacks, escalating privileges, or bypassing security controls. Organizations in sectors with stringent data protection requirements, such as finance, healthcare, and government, could face compliance risks under GDPR if sensitive data exposure leads to personal data compromise. Additionally, the vulnerability could undermine trust in internal calendaring or scheduling systems if exploited. Given the remote exploitability and lack of user interaction requirement, attackers could automate reconnaissance efforts against QuickCal deployments, increasing the risk of widespread information leakage within affected environments.

To mitigate this vulnerability, European organizations should first inventory their use of Themovation QuickCal and identify affected versions (up to 1.0.15). Although no patches are currently available, organizations should monitor Themovation's official channels for updates or security advisories. In the interim, restrict network access to QuickCal instances by implementing network segmentation and firewall rules to limit exposure to trusted users and systems only. Employ application-layer access controls and enforce least privilege principles to reduce the risk of unauthorized access. Conduct thorough security assessments and code reviews of QuickCal deployments to identify any exposed sensitive data and remove or encrypt embedded secrets where possible. Additionally, implement monitoring and logging to detect unusual access patterns or data retrieval attempts from QuickCal. If feasible, consider temporary replacement with alternative calendaring solutions that do not exhibit this vulnerability until a patch is released.
