Description : The .so library, which is used by , is vulnerable to a buffer overflow in the code that handles the deletion of certificates. This buffer overflow can be triggered by providing a long file path to the action of the .exe CGI binary or to the .sh CGI script. This binary or script will write this file path to , which is then read by .so This issue affects Iocharger firmware for AC models before version 24120701. Likelihood: Moderate – An attacker will have to find this exploit by either obtaining the binaries involved in this vulnerability, or by trial and error. Furthermore, the attacker will need a (low privilege) account to gain access to the .exe CGI binary or .sh script to trigger the vulnerability, or convince a user with such access send an HTTP request that triggers it. Impact: High – The process, which we assume is responsible for OCPP communication, will keep crashing after performing the exploit. This happens because the buffer overflow causes the process to segfault before is removed. This means that, even though is automatically restarted, it will crash again as soon as it tries to parse the text file. CVSS clarification. The attack can be executed over any network connection the station is listening to and serves the web interface (AV:N), and there are no additional security measure sin place that need to be circumvented (AC:L), the attack does not rely on preconditions (AT:N). The attack does require authentication, but the level of authentication is irrelevant (PR:L), it does not require user interaction (UI:N). The attack leads to reducred availability of the device (VC:N/VI:N/VA:H). THere is not impact on subsequent systems. (SC:N/SI:N/SA:N). Alltough this device is an EV charger handing significant amounts of power, we do not forsee a safety impact. The attack can be automated (AU:Y). Because the DoS condition is written to disk persistantly, it cannot be recovered by the user (R:I).
Severity: 0.0 | NA
