Last modified

CVE-2013-1802 is a vulnerability of currently unknown severity. The extlib gem 0.9.15 and earlier for Ruby does not properly restrict casts of string values, which might allow remote attackers to conduct object-injection attacks and execute arbitrary code, or cause a denial of service (memory and CPU consumption) by leveraging Action Pack support for (1) YAML type conversion or (2) Symbol type conversion, a similar vulnerability to CVE-2013-0156.. EPSS estimates a 3.42% chance of exploitation in the next 30 days.
