4.3 CVE-2026-12207
Enriched by CISA Buffer Overflow
A security flaw has been discovered in medkey-org medkey up to fc09b7ba9441ff590b72d428d5380834216b09ed. Impacted is the function actionGetPatientById of the file appmodulesmedicalportrestcontrollersPatientController.php of the component HTTP REST API. The manipulation of the argument ID results in improper control of resource identifiers. The attack may be performed from remote. The exploit has been released to the public and may be used for attacks. This product utilizes a rolling release system for continuous delivery, and as such, version information for affected or updated releases is not disclosed. The vendor was contacted early about this disclosure but did not respond in any way.

Categories
CWE-99 : Improper Control of Resource Identifiers ('Resource Injection')
The product receives input from an upstream component, but it does not restrict or incorrectly restricts the input before it is used as an identifier for a resource that may be outside the intended sphere of control. OWASP uses this term, although it is effectively the same as resource injection. Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.) chain: mobile OS verifies cryptographic signature of file in an archive, but then installs a different file with the same name that is also listed in the archive.

Buffer Overflow via Environment Variables
This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the adversary finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables. [Identify target application] The adversary identifies a target application or program to perform the buffer overflow on. In this attack the adversary looks for an application that loads the content of an environment variable into a buffer. [Find injection vector] The adversary identifies an injection vector to deliver the excessive content to the targeted application's buffer. [Craft overflow content] The adversary crafts the content to be injected. If the intent is to simply cause the software to crash, the content need only consist of an excessive quantity of random data. If the intent is to leverage the overflow for execution of arbitrary code, the adversary crafts the payload in such a way that the overwritten return address is replaced with one of the adversary's choosing. [Overflow the buffer] Using the injection vector, the adversary injects the crafted overflow content into the buffer. |

Resource Injection
An adversary exploits weaknesses in input validation by manipulating resource identifiers enabling the unintended modification or specification of a resource. |

Manipulating Writeable Configuration Files
Generally these are manually edited files that are not in the preview of the system administrators, any ability on the attackers' behalf to modify these files, for example in a CVS repository, gives unauthorized access directly to the application, the same as authorized users. |
