CVE-2011-1836

CVE-2011-1836 describes a local privilege escalation vulnerability in ecryptfs-utils versions prior to 90, specifically within the utils/ecryptfs-recover-private script. The flaw stems from the script failing to establish a subdirectory with secure permissions during the recovery process, potentially allowing local users to bypass intended access restrictions through standard filesystem operations. With a CVSS score of 4.6 (AV:L/AC:L/Au:N/C:P/I:P/A:P), this vulnerability has low attack complexity and requires local access, leading to potential confidentiality, integrity, and availability impacts. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage, suggesting it is not a widely targeted or discussed vulnerability.
