Detailsinfo

A vulnerability has been found in Iocharger and classified as problematic. Affected by this vulnerability is an unknown code block of the component Charging Station. The manipulation with an unknown input leads to a credentials storage vulnerability. The CWE definition for the vulnerability is CWE-256. Storing a password in plaintext may result in a system compromise. As an impact it is known to affect confidentiality. The summary by CVE is:

After gaining access to the firmware of a charging station, a file at can be accessed to obtain default credentials that are the same across all Iocharger AC model EV chargers. This issue affects Iocharger firmware for AC models before firmware version 25010801. The issue is addressed by requiring a mandatory password change on first login, it is still recommended to change the password on older models. Likelihood: Moderate – The attacker will first have to abuse a code execution or file inclusion vulnerability (for example by using .sh) to gain access to the .json file, or obtain a firmware dump of the charging station or obtain the firmware via other channels. Impact: Critical – All chargers using Iocharger firmware for AC models started with the same initial password. For models with firmware version before 25010801 a password change was not mandatory. It is therefore very likely that this firmware password is still active on many chargers. These credentials could, once obtained, allow an attacker to log into many Iocharger charging station, and allow them to execute arbitrary commands via the System → Custom page. CVSS clarification: Any network interface serving the web ui is vulnerable (AV:N) and there are not additional security measures to circumvent (AC:L), nor does the attack require and existing preconditions (AT:N). The attack is authenticated, and requires high privileges (PR:H), there is no user interaction required (UI:N). The attack leads to a compromised of the confidentialy of the "super user" credentials of the device (VC:H/VI:N/VA:N), and can subsequently be used to full compromise and other devices (SC:H/SI:H/SA:H). Becuase this is an EV charger handing significant power, there is a potential safety impact (S:P). This attack can be automated (AU:Y).

The weakness was released by Wilco Van Beijnum, Harm van den Brink and Frank Breedijk as DIVD-2024-00035. It is possible to read the advisory at csirt.divd.nl. This vulnerability is known as CVE-2024-43659 since 08/14/2024. Attacking locally is a requirement. The technical details are unknown and an exploit is not publicly available. The attack technique deployed by this issue is T1552 according to MITRE ATT&CK.

Upgrading to version 25010801 eliminates this vulnerability.
