Title source: llm
STIX 2.1

Exploitation Summary

EIP tracks 2 public exploits for CVE-2010-2063. PoCs published by Metasploit, Jun Mao, jduck, including Metasploit module exploits/linux/samba/chain_reply.

AI-analyzed exploit summary This exploit targets a memory corruption vulnerability in Samba versions prior to 3.3.13, specifically on Linux x86 systems without NX memory protection. It leverages a chained response packet to overwrite a talloc chunk destructor function pointer, achieving remote code execution.

Description

Buffer overflow in the SMB1 packet chaining implementation in the chain_reply function in process.c in smbd in Samba 3.0.x before 3.3.13 allows remote attackers to cause a denial of service (memory corruption and daemon crash) or possibly execute arbitrary code via a crafted field in a packet.
