CVE-2023-25109

CVSS v2.0

9.0

High

VectorAV:N/AC:L/Au:S/C:C/I:C/A:C
Name of the Vulnerable Software and Affected Versions Milesight UR32L version 32.3.0.5
Description Multiple buffer overflow vulnerabilities exist in the vtysh ubus binary due to the use of an unsafe sprintf pattern. A specially crafted HTTP request can lead to arbitrary code execution. An attacker with high privileges can send HTTP requests to trigger these vulnerabilities. This buffer overflow occurs in the set gre function with the local ip variable.
Recommendations For Milesight UR32L version 32.3.0.5, as a temporary workaround, consider disabling the set gre function until a patch is available. Restrict access to the vtysh ubus binary to minimize the risk of exploitation. Avoid using the local ip variable in the affected API endpoint until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
