Improper Link Resolution Before File Access ('Link Following')

A vulnerability in the web-based UI of Cisco Unified Communications Manager could allow an unauthenticated, remote attacker to execute a cross-frame scripting (XFS) attack. The vulnerability exists because the affected software does not provide sufficient protections for HTML inline frames (iframes). An attacker could exploit this vulnerability by directing a user of the affected software to an attacker-controlled web page that contains a malicious HTML inline frame. A successful exploit could allow the attacker to conduct click-jacking or other types of client-side browser attacks. Cisco Bug IDs: CSCve60993.Show less

A flaw was found in instack-undercloud 7.2.0 as packaged in Red Hat OpenStack Platform Pike, 6.1.0 as packaged in Red Hat OpenStack Platform Oacta, 5.3.0 as packaged in Red Hat OpenStack Newton, where pre-install and security policy scripts used insecure temporary files. A local user could exploit this flaw to conduct a symbolic-link attack, allowing them to overwrite the contents of arbitrary files.Show less

mktexlsr revision 36855, and before revision 36626 as packaged in texlive allows local users to write to arbitrary files via a symlink attack. NOTE: this vulnerability exists due to the reversion of a fix of CVE-2015-5700.Show less

The _write_config function in trove/guestagent/datastore/experimental/mongodb/service.py, reset_configuration function in trove/guestagent/datastore/experimental/postgresql/service/config.py, write_config function in trove/guestagent/datastore/experimental/redis/service.py, _write_mycnf function in trove/guestagent/datastore/mysql/service.py, InnoBackupEx::_run_prepare function in trove/guestagent/strategies/restore/mysql_impl.py, InnoBackupEx::cmd function in trove/guestagent/strategies/backup/mysql_impl.py, MySQLDump::cmd in trove/guestagent/strategies/backup/mysql_impl.py, InnoBackupExIncremental::cmd function in trove/guestagent/strategies/backup/mysql_impl.py, _get_actual_db_status function in trove/guestagent/datastore/experimental/cassandra/system.py and trove/guestagent/datastore/experimental/cassandra/service.py, and multiple class CbBackup methods in trove/guestagent/strategies/backup/experimental/couchbase_impl.py in Openstack DBaaS (aka Trove) as packaged in Openstack before 2015.1.0 (aka Kilo) allows local users to write to configuration files via a symlink attack on a temporary file.Show less

Automatic Bug Reporting Tool (ABRT) allows local users to read, change the ownership of, or have other unspecified impact on arbitrary files via a symlink attack on (1) /var/tmp/abrt/*/maps, (2) /tmp/jvm-*/hs_error.log, (3) /proc/*/exe, (4) /etc/os-release in a chroot, or (5) an unspecified root directory related to librpm.Show less

In the cron package through 3.0pl1-128 on Debian, and through 3.0pl1-128ubuntu2 on Ubuntu, the postinst maintainer script allows for group-crontab-to-root privilege escalation via symlink attacks against unsafe usage of the chown and chmod programs.Show less

An issue was discovered in certain Apple products. iOS before 10.3.2 is affected. macOS before 10.12.5 is affected. The issue involves the "iBooks" component. It allows attackers to execute arbitrary code in a privileged context via a crafted app that uses symlinks.Show less

perltidy through 20160302, as used by perlcritic, check-all-the-things, and other software, relies on the current working directory for certain output files and does not have a symlink-attack protection mechanism, which allows local users to overwrite arbitrary files by creating a symlink, as demonstrated by creating a perltidy.ERR symlink that the victim cannot delete.Show less

ProFTPD before 1.3.5e and 1.3.6 before 1.3.6rc5 controls whether the home directory of a user could contain a symbolic link through the AllowChrootSymlinks configuration option, but checks only the last path component when enforcing AllowChrootSymlinks. Attackers with local access could bypass the AllowChrootSymlinks control by replacing a path component (other than the last one) with a symbolic link. The threat model includes an attacker who is not granted full filesystem access by a hosting provider, but can reconfigure the home directory of an FTP user.Show less
