EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description

Multiple heap-based buffer overflows in the NDR parsing in smbd in Samba 3.0.0 through 3.0.25rc3 allow remote attackers to execute arbitrary code via crafted MS-RPC requests involving (1) DFSEnum (netdfs_io_dfs_EnumInfo_d), (2) RFNPCNEX (smb_io_notify_option_type_data), (3) LsarAddPrivilegesToAccount (lsa_io_privilege_set), (4) NetSetFileSecurity (sec_io_acl), or (5) LsarLookupSids/LsarLookupSids2 (lsa_io_trans_names).

Exploits & PoCs

Research use only. For defensive security, authorized penetration testing, and academic research only. Never execute exploit code against systems without explicit written authorization.
