Nmap
Monthly
Out-of-bounds reads and a process crash in Nmap through 7.99 can be triggered remotely by any host that is being scanned, or by an on-path attacker, via a crafted IPv6 packet with a truncated extension header. The root cause is an integer underflow in the `ipv6_get_data_primitive` function (libnetutil/netutil.cc) where an insufficiently strict bounds check allows the extension-header walk pointer to advance past the captured packet buffer, causing the remaining-length subtraction to wraparound to a very large value. A publicly available exploit proof-of-concept exists; this vulnerability is not currently listed in the CISA KEV catalog.
An issue was discovered in Npcap 0.992. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. Public exploit code available and no vendor patch available.
Nmap through 7.70, when the -sV option is used, allows remote attackers to cause a denial of service (stack consumption and application crash) via a crafted TCP-based service. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
nmap version 6.49BETA6 through 7.60, up to and including SVN revision 37147 contains a Directory Traversal vulnerability in NSE script http-fetch that can result in file overwrite as the user is. Rated medium severity (CVSS 5.7), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
The http-domino-enum-passwords.nse script in NMap before 6.40, when domino-enum-passwords.idpath is set, allows remote servers to upload "arbitrarily named" files via a crafted FullName parameter in. Rated medium severity (CVSS 6.8), this vulnerability is remotely exploitable. Public exploit code available.
