CyberRota Analysis
AI-GeneratedDBD::DBM versions prior to 1.653 for Perl are vulnerable to arbitrary module loading due to insufficient validation of the dbm_type and dbm_mldbm attributes, allowing attackers to execute arbitrary code by manipulating these parameters in a connection string. This vulnerability poses a significant risk for applications that allow untrusted input to influence database connection configurations, potentially leading to remote code execution. Organizations using affected versions of DBI should prioritize patching to mitigate this risk, especially those handling sensitive data or operating in untrusted environments.

Original NVD Description
DBI versions before 1.653 for Perl load arbitrary modules via unvalidated dbm_type and dbm_mldbm attributes in DBD::DBM. DBD::DBM passes the dbm_type and dbm_mldbm connect attributes to require without checking that the value names a module. require treats a path-shaped string as a literal filename and does not consult @INC, so the attribute chooses the file that Perl loads and runs. The MLDBM::Serializer:: prefix that DBD::DBM prepends to dbm_mldbm is not a boundary: only the :: separators are rewritten to /, so a value containing / traverses out of the serializer directory. The value is also assigned to $MLDBM::Serializer, which MLDBM requires the same way when it ties the table. A caller that lets an untrusted party influence either attribute, for example through a DSN fragment or a parameter that selects a storage backend, runs the file-scope code of whatever module the value names. For example, my $dsn = "dbi:DBM:f_dir=/var/db;dbm_type=../../Untrusted.pm" my $dbh = DBI->connect( $dsn ); Note that DBD::Gofer forwards connect attributes to the server side, and DBI::ProxyServer checks only that a DSN starts with a driver prefix.
