Search Vulnerabilities

A Path traversal vulnerability has been reported in elijaa/phpmemcachedadmin affecting version 1.3.0. This vulnerability allows an attacker to delete files stored on the server due to lack of proper verification of user-supplied input.

In Memcached before 1.6.22, a buffer overflow exists when processing multiget requests in proxy mode, if there are many spaces after the "get" substring.

In Memcached before 1.6.22, an off-by-one error exists when processing proxy requests in proxy mode, if \n is used instead of \r\n.

Cross-Site Request Forgery (CSRF) vulnerability in Palasthotel (in person: Edward Bock) Use Memcached plugin <= 1.0.4 versions.

memcached 1.6.7 allows a Denial of Service via multi-packet uploads in UDP.

Memcached 1.6.0 before 1.6.3 allows remote attackers to cause a denial of service (daemon crash) via a crafted meta command.

libmemcached-awesome is an open source C/C++ client library and tools for the memcached server. `libmemcached` could return data for a previously requested key, if that previous request timed out due to a low `POLL_TIMEOUT`. This issue has been addressed in version 1.1.4. Users are advised to upgrade. There are several ways to workaround or lower the probability of this bug affecting a given deployment. 1: use a reasonably high `POLL_TIMEOUT` setting, like the default. 2: use separate libmemcached connections for unrelated data. 3: do not re-use libmemcached connections in an unknown state.

Buffer Overflow vulnerability in authfile.c memcached 1.6.9 allows attackers to cause a denial of service via crafted authenticattion file.

PHP-Memcached v2.2.0 and below contains an improper NULL termination which allows attackers to execute CLRF injection. Note: Third parties have disputed this as not affecting PHP-Memcached directly.

The official memcached docker images before 1.5.11-alpine (Alpine specific) contain a blank password for a root user. System using the memcached docker container deployed by affected versions of the docker image may allow a remote attacker to achieve root access with a blank password.

Memcached 1.6.x before 1.6.2 allows remote attackers to cause a denial of service (daemon crash) via a crafted binary protocol header to try_read_command_binary in memcached.c.

memcached 1.5.16, when UNIX sockets are used, has a stack-based buffer over-read in conn_to_str in memcached.c.

In memcached before 1.5.14, a NULL pointer dereference was found in the "lru mode" and "lru temp_ttl" commands. This causes a denial of service when parsing crafted lru command messages in process_lru_command in memcached.c.

memcached version prior to 1.4.37 contains an Integer Overflow vulnerability in items.c:item_free() that can result in data corruption and deadlocks due to items existing in hash table being reused from free list. This attack appear to be exploitable via network connectivity to the memcached service. This vulnerability appears to have been fixed in 1.4.37 and later.

Memcached version 1.5.5 contains an Insufficient Control of Network Message Volume (Network Amplification, CWE-406) vulnerability in the UDP support of the memcached server that can result in denial of service via network flood (traffic amplification of 1:50,000 has been reported by reliable sources). This attack appear to be exploitable via network connectivity to port 11211 UDP. This vulnerability appears to have been fixed in 1.5.6 due to the disabling of the UDP protocol by default.
