Vulnerability Title
Buffer overflow in <redacted>.so leads to DoS of OCPP service
来源: CVE Program / CVE List V5
Vulnerability Description
The <redacted>.so library, which is used by <redacted>, 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 <redacted> action of the <redacted>.exe CGI binary or
to the <redacted>.sh CGI script. This binary or script will write this
file path to <redacted>, which is then
read by <redacted>.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 <redacted>.exe CGI binary or <redacted>.sh
script to trigger the vulnerability, or convince a user with such access
send an HTTP request that triggers it.
Impact: High – The <redacted> 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
<redacted> is removed. This means that,
even though <redacted> 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).
