security flaw

The attachment scrubber (Scrubber.py) in Mailman 2.1.5 and earlier, when using Python's library email module 2.5, allows remote attackers to cause a denial of service (mailing list delivery failure) via a multipart MIME message with a single part that has two blank lines between the first boundary and the end boundary.

Cross-site scripting (XSS) vulnerability in the private archive script (private.py) in GNU Mailman 2.1.7 allows remote attackers to inject arbitrary web script or HTML via the action argument.

Format string vulnerability in Mailman before 2.1.9 allows attackers to execute arbitrary code via unspecified vectors. NOTE: the vendor has disputed this vulnerability, stating that it is "unexploitable.

security flaw

Mailman before 2.1.9rc1 allows remote attackers to cause a denial of service via unspecified vectors involving "standards-breaking RFC 2231 formatted headers".

security flaw

Multiple cross-site scripting (XSS) vulnerabilities in Mailman before 2.1.9rc1 allow remote attackers to inject arbitrary web script or HTML via unspecified vectors.

mailman logfile CRLF injection

CRLF injection vulnerability in Utils.py in Mailman before 2.1.9rc1 allows remote attackers to spoof messages in the error log and possibly trick the administrator into visiting malicious URLs via CRLF sequences in the URI.

GNU Mailman 2.1.39, as bundled in cPanel (and WHM), allows unauthenticated attackers to create lists via the /mailman/create endpoint. NOTE: multiple third parties report that they are unable to reproduce this, regardless of whether cPanel or WHM is used.

GNU Mailman 2.1.39, as bundled in cPanel (and WHM), in certain external archiver configurations, allows unauthenticated attackers to execute arbitrary OS commands via shell metacharacters in an email Subject line. NOTE: multiple third parties report that they are unable to reproduce this, regardless of whether cPanel or WHM is used.

GNU Mailman 2.1.39, as bundled in cPanel (and WHM), allows unauthenticated attackers to read arbitrary files via ../ directory traversal at /mailman/private/mailman (aka the private archive authentication endpoint) via the username parameter. NOTE: multiple third parties report that they are unable to reproduce this, regardless of whether cPanel or WHM is used.

mailman: directory traversal in MTA transports that deliver programmatically

Directory traversal vulnerability in GNU Mailman before 2.1.20, when not using a static alias, allows remote attackers to execute arbitrary files via a .. (dot dot) in a list name.

mailman: CSRF protection missing in the user options page

Cross-site request forgery (CSRF) vulnerability in the user options page in GNU Mailman 2.1.x before 2.1.23 allows remote attackers to hijack the authentication of arbitrary users for requests that modify an option, as demonstrated by gaining access to the credentials of a victim's account.

mailman: Missing CSRF protection in admin web interface

Cross-site request forgery (CSRF) vulnerability in the admin web interface in GNU Mailman before 2.1.15 allows remote attackers to hijack the authentication of administrators.

mailman: Multiple security flaws leading to cross-site scripting (XSS) attacks

Multiple cross-site scripting (XSS) vulnerabilities in GNU Mailman before 2.1.14rc1 allow remote authenticated users to inject arbitrary web script or HTML via vectors involving (1) the list information field or (2) the list description field.

Mailman: Three XSS flaws due improper escaping of the full name of the member

Multiple cross-site scripting (XSS) vulnerabilities in Cgi/confirm.py in GNU Mailman 2.1.14 and earlier allow remote attackers to inject arbitrary web script or HTML via the (1) full name or (2) username field in a confirmation message.

Cross-site scripting (XSS) vulnerability in mmsearch/design in the Mailman/htdig integration patch for Mailman allows remote attackers to inject arbitrary web script or HTML via the config parameter.

mailman: password checking timing attack in administrative REST API

An issue was discovered in Mailman Core before 3.3.5. An attacker with access to the REST API could use timing attacks to determine the value of the configured REST API password and then make arbitrary REST API calls. The REST API is bound to localhost by default, limiting the ability for attackers to exploit this, but can optionally be made to listen on other interfaces.

mailman: CSRF token bypass allows to perform CSRF attacks and admin takeover

In GNU Mailman before 2.1.38, a list member or moderator can get a CSRF token and craft an admin request (using that token) to set a new admin password or make other changes.

mailman: a list moderator can crack the list admin password encrypted in a CSRF token

In GNU Mailman before 2.1.36, the CSRF token for the Cgi/admindb.py admindb page contains an encrypted version of the list admin password. This could potentially be cracked by a moderator via an offline brute-force attack.

mailman: XSS in Cgi/options.py via crafted URL

In GNU Mailman before 2.1.36, a crafted URL to the Cgi/options.py user options page can execute arbitrary JavaScript for XSS.

mailman: CSRF token bypass allows to perform CSRF attacks and account takeover

GNU Mailman before 2.1.35 may allow remote Privilege Escalation. A csrf_token value is not specific to a single user account. An attacker can obtain a value within the context of an unprivileged user account, and then use that value in a CSRF attack against an admin (e.g., for account takeover).
