Vulnerabilities

Nmap through 7.99 does not keep the IPv6 extension-header walk within the captured packet in ipv6_get_data_primitive (libnetutil/netutil.cc), so the pointer advances past the buffer and the remaining-length computation underflows to a large value. A scanned target or on-path attacker returning a crafted IPv6 response with a truncated extension header can trigger out-of-bounds reads and a crash during raw IPv6 scans.

In the python-libnmap package through 0.7.2 for Python, remote command execution can occur (if used in a client application that does not validate arguments). NOTE: the vendor believes it would be unrealistic for an application to call NmapProcess with arguments taken from input data that arrived over an untrusted network, and thus the CVSS score corresponds to an unrealistic use case. None of the NmapProcess documentation implies that this is an expected use case

nse_libssh2.cc in Nmap 7.70 is subject to a denial of service condition due to a double free when an SSH connection fails, as demonstrated by a leading \n character to ssh-brute.nse or ssh-auth-methods.nse.

libnmap < v0.6.3 is affected by: XML Injection. The impact is: Denial of service (DoS) by consuming resources. The component is: XML Parsing. The attack vector is: Specially crafted XML payload.

In Webbukkit Dynmap 3.0-beta-3 or below, due to a missing login check in servlet/MapStorageHandler.java, an attacker can see a map image without login even if victim enables login-required in setting.

An issue was discovered in Npcap 0.992. Sending a malformed .pcap file with the loopback adapter using either pcap_sendqueue_queue() or pcap_sendqueue_transmit() results in kernel pool corruption. This could lead to arbitrary code executing inside the Windows kernel and allow escalation of privileges.

A command injection vulnerability in libnmapp package for versions <0.4.16 allows arbitrary commands to be executed via arguments to the range options.

nmap4j 1.1.0 allows attackers to execute arbitrary commands via shell metacharacters in an includeHosts call.

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.

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 running it. This attack appears to be exploitable via a victim that runs NSE script http-fetch against a malicious web site. This vulnerability appears to have been fixed in 7.7.
