Vulnerabilities

dhcpcd through 10.3.2, fixed in commit 708b4a5, contains a memory leak vulnerability in the IPv6 Router Advertisement route information handling that allows an unauthenticated same-link attacker to cause denial of service by sending crafted Router Advertisements. Attackers can repeatedly send Router Advertisements containing Route Information options with a lifetime of zero, triggering unfreed allocations in routeinfo_findalloc() that cause linear memory exhaustion and eventual daemon crash.

dhcms v20170919 was discovered to contain an arbitrary folder deletion vulnerability via /admin.php?r=admin/AdminBackup/del.

DHC Vision eQMS through 5.4.8.322 has Persistent XSS due to insufficient encoding of untrusted input/output. To exploit the vulnerability, the attacker has to create or edit a new information object and use the XSS payload as the name. Any user that opens the object's version or history tab will be attacked.

A Cross SIte Scripting (XSS) vulnerability exists in Dhcms 2017-09-18 in guestbook via the message board, which could let a remote malicious user execute arbitrary code.

An issue was discovered in Dual DHCP DNS Server 7.40. Due to insufficient access restrictions in the default installation directory, an attacker can elevate privileges by replacing the DualServer.exe binary.

Issues were discovered in Open DHCP Server (Regular) 1.75 and Open DHCP Server (LDAP Based) 0.1Beta. Due to insufficient access restrictions in the default installation directory, an attacker can elevate privileges by replacing the OpenDHCPServer.exe (Regular) or the OpenDHCPLdap.exe (LDAP Based) binary.

dhcp6.c in dhcpcd before 6.11.7 and 7.x before 7.2.2 has a buffer over-read in the D6_OPTION_PD_EXCLUDE feature.

dhcpcd before 7.2.1 contains a buffer overflow in dhcp6_findna in dhcp6.c when reading NA/TA addresses.

DhCms through 2017-09-18 has admin.php?r=admin/Index/index XSS.

The DHC Online Shop App for Android version 3.2.0 and earlier does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

dhcpcd before 6.10.0 allows remote attackers to cause a denial of service (invalid read and crash) via vectors related to the option length.

dhcpcd before 6.10.0, as used in Android 4.x before 4.4.4, 5.0.x before 5.0.2, 5.1.x before 5.1.1, and 6.x before 2016-04-01 and other products, mismanages option lengths, which allows remote attackers to execute arbitrary code or cause a denial of service (heap-based buffer overflow) via a malformed DHCP response, aka internal bug 26461634.
