CVE-2009-1255 describes an information disclosure vulnerability in Memcached versions prior to 1.2.8 and MemcacheDB 1.2.0. Attackers can retrieve sensitive system information, specifically the contents of /proc/self/maps and memory-allocation statistics, by sending specific commands to the daemon's TCP port. This allows remote attackers to bypass Address Space Layout Randomization (ASLR) protections. The vulnerability has a CVSS score of 5.0 (Medium), indicating a network-based attack with low complexity and no authentication required, leading to partial confidentiality impact. There is no impact on integrity or availability. Currently, there is no known active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE. It is not listed in the CISA KEV catalog.
