RoundCube Webmail

Cross Site Scripting (XSS) vulnerability in Roundcube Mail <=1.4.4 via smtp config in /installer/test.php.

In Roundcube Webmail before 1.6.18 and 1.7.x before 1.7.3, the "Add to address book" action was subject to stored XSS.

Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 allows the ImageMagick resource limits to be bypassed during thumbnail generation. When rcube_image falls back to GD, the available-memory check was applied only on Windows, so on other platforms a crafted image with large dimensions was processed by GD without any resource limit and could exhaust server memory. Upstream fixed this in the commit “Fix ImageMagick resource limits bypass by GD fallback during thumbnail generation”, which applies the memory check on all platforms.

Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 is affected by an uncontrolled resource consumption vulnerability in the CSS proxy (the utils/modcss action). The fetched stylesheet was read into memory in full, with no size limit and no read timeout, so a stylesheet URL referencing an attacker-controlled host could be used to exhaust server memory. Upstream fixed this in the commit “Add a size limit to the CSS proxy content processing”, which caps the response at 5 MB, reads it as a stream and applies a read timeout.

An issue was discovered in Roundcube Webmail before 1.5.14 and 1.6.14. The remote image blocking feature can be bypassed via a crafted background attribute of a BODY element in an e-mail message. This may lead to information disclosure or access-control bypass.

An issue was discovered in Roundcube Webmail before 1.5.14 and 1.6.14. The remote image blocking feature can be bypassed via SVG content (with animate attributes) in an e-mail message. This may lead to information disclosure or access-control bypass.

An issue was discovered in Roundcube Webmail before 1.5.14 and 1.6.14. Insufficient Cascading Style Sheets (CSS) sanitization in HTML e-mail messages may lead to a fixed-position mitigation bypass via the use of !important.

Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 is affected by a remote content blocking bypass. rcube_washtml inspected the SVG SMIL animation attributes `to`, `from` and values for URIs, but not `by`; so markup such as in an HTML message caused remote content to be loaded without the user's consent, disclosing the client IP address and confirming that the message was opened. Upstream fixed this in the commit “Fix remote-content blocker bypass via SVG SMIL `by` attribute”.

Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 is affected by a remote content blocking bypass in the handling of FuncIRI attributes. rcube_washtml detected the CSS url() token with a pattern that enumerated only some of its escaped spellings, so values using other CSS escape sequences, for example \000075rl( or u\72 l(, were not recognized and remote content was loaded from an HTML message without the user's consent. Upstream fixed this in the commit “Fix remote content blocking bypass via CSS escapes in FuncIRI attributes (again)”, which resolves CSS escapes before matching and also inspects the `to`, `from` and `by` attributes.

Absolute path traversal vulnerability in steps/mail/sendmail.inc in Roundcube Webmail before 0.7.3 and 0.8.x before 0.8.6 allows remote attackers to read arbitrary files via a full pathname in the _value parameter for the generic_message_footer setting in a save-perf action to index.php, as exploited in the wild in March 2013.

include/iniset.php in Roundcube Webmail 0.5.4 and earlier, when PHP 5.3.7 or 5.3.8 is used, allows remote attackers to trigger a GET request for an arbitrary URL, and cause a denial of service (resource consumption and inbox outage), via a Subject header containing only a URL, a related issue to CVE-2011-3379.

Roundcube 0.3.1 and earlier does not request that the web browser avoid DNS prefetching of domain names contained in e-mail messages, which makes it easier for remote attackers to determine the network location of the webmail user by logging DNS requests.

roundcube webmail Alpha, with a default high verbose level ($rcmail_config['debug_level'] = 1), allows remote attackers to obtain the full path of the application via an invalid_task parameter, which leaks the path in an error message.

Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 is affected by a mail header injection vulnerability. rcmail_sendmail stripped newline characters only from the Subject and Organization headers, leaving other header values taken from request parameters unsanitized, so a remote authenticated attacker could inject arbitrary headers into an outgoing message via the References, In-Reply-To, Message-ID and From parameters. Upstream fixed this in the commit “Fix mail header injection via References/In-Reply-To/Message-ID/From parameters”, which normalizes whitespace in every string header value.

Cross-site scripting (XSS) vulnerability in RoundCube webmail 0.1rc2, 2007-12-09, and earlier versions, when using Internet Explorer, allows remote attackers to inject arbitrary web script or HTML via style sheets containing expression commands.

Cross-site scripting (XSS) vulnerability in program/lib/washtml.php in Roundcube Webmail 0.8.0 allows remote attackers to inject arbitrary web script or HTML by using "javascript:" in an href attribute in the body of an HTML-formatted email.

Cross-site scripting (XSS) vulnerability in Roundcube Webmail 0.8.1 and earlier allows remote attackers to inject arbitrary web script or HTML via the signature in an email.

program/lib/Roundcube/rcube_washtml.php in Roundcube before 1.0.5 does not properly quote strings, which allows remote attackers to conduct cross-site scripting (XSS) attacks via the style attribute in an email.

Cross-site scripting (XSS) vulnerability in the UI messages functionality in Roundcube Webmail before 0.5.4 allows remote attackers to inject arbitrary web script or HTML via the _mbox parameter to the default URI.

Cross-site scripting (XSS) vulnerability in Roundcube Webmail before 0.8.5 allows remote attackers to inject arbitrary web script or HTML via a (1) data:text or (2) vbscript link.

Cross-site scripting (XSS) vulnerability in RoundCube Webmail (roundcubemail) 0.2 stable allows remote attackers to inject arbitrary web script or HTML via the background attribute embedded in an HTML e-mail message.

Multiple cross-site scripting (XSS) vulnerabilities in Roundcube webmail before 0.9.3 allow user-assisted remote attackers to inject arbitrary web script or HTML via the body of a message visited in (1) new or (2) draft mode, related to compose.inc; and (3) might allow remote authenticated users to inject arbitrary web script or HTML via an HTML signature, related to save_identity.inc.

In Roundcube Webmail before 1.3.10, an attacker in possession of S/MIME or PGP encrypted emails can wrap them as sub-parts within a crafted multipart email. The encrypted part(s) can further be hidden using HTML/CSS or ASCII newline characters. This modified multipart email can be re-sent by the attacker to the intended receiver. If the receiver replies to this (benign looking) email, they unknowingly leak the plaintext of the encrypted message part(s) back to the attacker.

In Roundcube Webmail before 1.6.18 and 1.7.x before 1.7.3, improper rule name quoting could lead to managesieve_disabled_actions setting bypass via a crafted rule name in a Sieve script. This issue only affects Roundcube instances using the managesieve plugin.

Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 is affected by a CSRF validation bypass in the mark-as-junk action of the markasjunk plugin. The plugin read the _uid parameter from POST data but passed it to rcmail::get_uids() without constraining the input mode, so values re-read inside that helper could be taken from the query string and the action carried out without a valid CSRF token. Upstream fixed this in the commit “Fix CSRF validation bypass in the mark-as-junk action”, which passes rcube_utils::INPUT_POST explicitly.

An issue was discovered in Roundcube Webmail before 1.5.14 and 1.6.14. Incorrect password comparison in the password plugin could lead to type confusion that allows a password change without knowing the old password.

The login form in Roundcube Webmail before 0.5.1 does not properly handle a correctly authenticated but unintended login attempt, which makes it easier for remote authenticated users to obtain sensitive information by arranging for a victim to login to the attacker's account and then compose an e-mail message, related to a "login CSRF" issue.

Cross-site scripting (XSS) vulnerability in program/js/app.js in Roundcube webmail before 1.0.7 and 1.1.x before 1.1.3 allows remote authenticated users to inject arbitrary web script or HTML via the file name in a drag-n-drop file upload.

Cross-site scripting (XSS) vulnerability in Roundcube webmail 1.0-git allows remote authenticated users to inject arbitrary web script or HTML via the Name field of an addressbook group.

An issue was discovered in Roundcube Webmail before 1.5.14 and 1.6.14. Unsanitized IMAP SEARCH command arguments could lead to IMAP injection or CSRF bypass during mail search.

Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 allows the disabled_actions configuration setting to be bypassed. The check compared only the action name as requested, so a remote authenticated attacker could reach an action listed in disabled_actions by requesting it through its deprecated alias instead. Upstream fixed this in the commit “Fix bug where deprecated action aliases bypassed `disabled_actions` setting”, which moves the check into rcmail::action_handler() and resolves aliases before comparing.

Cross-site scripting (XSS) vulnerability in program/steps/mail/func.inc in RoundCube Webmail before 0.8.0, when using the Larry skin, allows remote attackers to inject arbitrary web script or HTML via the email message subject.

Cross-site scripting (XSS) vulnerability in Roundcube Webmail before 0.7, when Internet Explorer is used, allows remote attackers to inject arbitrary web script or HTML via vectors involving an embedded image attachment.
