Description

This security bulletin contains information about 1 vulnerability.


1) Use of uninitialized resource (CVE-ID: N/A)

CWE-ID: CWE-908 - Use of Uninitialized Resource

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to disclose sensitive information.

The vulnerability exists due to uninitialized memory exposure in the SNMP OID encoding and varbind reply generation logic when processing specially crafted SNMP requests with non-minimal OID sub-identifiers. A remote attacker can send a specially crafted request for an absent OID to disclose sensitive information.

On UDP, the leaked data can contain a previous response sent to another client, including echoed community strings. On TCP, a later request on the same connection leaks only that connection\'s previous response.
