CVE-2013-2178 1 Fail2ban 1 Fail2ban 2017-09-19 5.0 MEDIUM N/A
The apache-auth.conf, apache-nohome.conf, apache-noscript.conf, and apache-overflows.conf files in Fail2ban before 0.8.10 do not properly validate log messages, which allows remote attackers to block arbitrary IP addresses via certain messages in a request.
CVE-2006-6302 1 Fail2ban 1 Fail2ban 2017-07-29 5.0 MEDIUM N/A
fail2ban 0.7.4 and earlier does not properly parse sshd log files, which allows remote attackers to add arbitrary hosts to the /etc/hosts.deny file and cause a denial of service by adding arbitrary IP addresses to the sshd log file, as demonstrated by logging in via ssh with a login name containing certain strings with an IP address.
CVE-2013-7177 1 Fail2ban 1 Fail2ban 2014-11-19 5.0 MEDIUM N/A
config/filter.d/cyrus-imap.conf in the cyrus-imap filter in Fail2ban before 0.8.11 allows remote attackers to trigger the blocking of an arbitrary IP address via a crafted e-mail address that matches an improperly designed regular expression.
CVE-2013-7176 1 Fail2ban 1 Fail2ban 2014-11-19 5.0 MEDIUM N/A
config/filter.d/postfix.conf in the postfix filter in Fail2ban before 0.8.11 allows remote attackers to trigger the blocking of an arbitrary IP address via a crafted e-mail address that matches an improperly designed regular expression.
CVE-2009-5023 1 Fail2ban 1 Fail2ban 2014-06-24 4.7 MEDIUM N/A
The (1) dshield.conf, (2) mail-buffered.conf, (3) mynetwatchman.conf, and (4) mynetwatchman.conf actions in action.d/ in Fail2ban before 0.8.5 allows local users to write to arbitrary files via a symlink attack on temporary files with predictable names, as demonstrated by /tmp/fail2ban-mail.txt.
CVE-2012-5642 1 Fail2ban 1 Fail2ban 2013-12-05 7.5 HIGH N/A
server/action.py in Fail2ban before 0.8.8 does not properly handle the content of the matches tag, which might allow remote attackers to trigger unsafe behavior in a custom action file via unspecified symbols in this content.
CVE-2007-4321 1 Fail2ban 1 Fail2ban 2012-10-31 6.8 MEDIUM N/A
fail2ban 0.8 and earlier does not properly parse sshd log files, which allows remote attackers to add arbitrary hosts to the /etc/hosts.deny file and cause a denial of service by adding arbitrary IP addresses to the sshd log file, as demonstrated by logging in via ssh with a client protocol version identification containing an IP address string, a different vector than CVE-2006-6302.
CVE-2009-0362 1 Fail2ban 1 Fail2ban 2009-02-13 4.0 MEDIUM N/A
filter.d/wuftpd.conf in Fail2ban 0.8.3 uses an incorrect regular expression that allows remote attackers to cause a denial of service (forced authentication failures) via a crafted reverse-resolved DNS name (rhost) entry that contains a substring that is interpreted as an IP address, a different vulnerability than CVE-2007-4321.
