Actively exploited in the wild
ownCloud graphapi Information Disclosure Vulnerability
ownCloud - ownCloud graphapi · Listed in the CISA KEV since 2023-11-30. This indicates confirmed attacks in production environments.
Required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
CVE-2023-49103
CriticalCVSS 10.0KEVSummary
An issue was discovered in ownCloud owncloud/graphapi 0.2.x before 0.2.1 and 0.3.x before 0.3.1. The graphapi app relies on a third-party GetPhpInfo.php library that provides a URL. When this URL is accessed, it reveals the configuration details of the PHP environment (phpinfo). This information includes all the environment variables of the webserver. In containerized deployments, these environment variables may include sensitive data such as the ownCloud admin password, mail server credentials, and license key.
Risk Assessment
An attacker can obtain sensitive information such as passwords and keys, leading to unauthorized access and further compromise.
Recommendation
Update graphapi to version 0.2.1 or 0.3.1, or if not possible, disable the graphapi app and consider rotating exposed credentials.

A vulnerability in the ash_authentication library (Elixir) allows an attacker who can plant a remember-me cookie in a victim's browser to replace the victim's authenticated session with one for the attacker's own account. The issue stems from a mismatch between the session keys used by the guard and the reader, causing remember-me sign-in to run on every request.
Original NVD description (English source)
An issue was discovered in ownCloud owncloud/graphapi 0.2.x before 0.2.1 and 0.3.x before 0.3.1. The graphapi app relies on a third-party GetPhpInfo.php library that provides a URL. When this URL is accessed, it reveals the configuration details of the PHP environment (phpinfo). This information includes all the environment variables of the webserver. In containerized deployments, these environment variables may include sensitive data such as the ownCloud admin password, mail server credentials, and license key. Simply disabling the graphapi app does not eliminate the vulnerability. Additionally, phpinfo exposes various other potentially sensitive configuration details that could be exploited by an attacker to gather information about the system. Therefore, even if ownCloud is not running in a containerized environment, this vulnerability should still be a cause for concern. Note that Docker containers from before February 2023 are not vulnerable to the credential disclosure.
