Overview
A vulnerability has been identified in Faucet SDN Ryu version 4.34, tracked as CVE-2024-34487. The vulnerability affects the OFPFlowStats component in the parser.py file, which can be exploited to cause a denial of service condition through an infinite loop when inst.length is set to 0 (GitHub Issue).
Technical details
The vulnerability exists in the OFPFlowStats parser implementation within parser.py (around line 4083) of Faucet SDN Ryu 4.34. The issue occurs in a while loop that processes instructions where if inst.length is set to 0, the offset will no longer change, resulting in an infinite loop. The vulnerability has been assigned a CVSS v3.1 score of 7.5 (High) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H. The weakness has been categorized as CWE-835 (Loop with Unreachable Exit Condition) (NVD).
Impact
The successful exploitation of this vulnerability results in a denial of service condition, effectively causing the affected component to enter an infinite loop, which can impact the availability of the system (NVD).
