Vulnerabilidades

Mojolicious versions from 4.59 before 9.48 for Perl expose a stable representation of the session CSRF token to a BREACH compression oracle. _csrf_token generates and caches one token per session and returns the same value on every call, and _csrf_field places that value in a hidden `csrf_token` input. When a response…

Mojolicious::Plugin::Web::Auth::OAuth2 versions through 0.17 for Perl have an insecure default state parameter. When no state generator is specified in the constructor, the module defaults to using a SHA-1 hash of predictable and low-entropy sources, including the epoch time (which is leaked via the HTTP Date header)…

Mojolicious::Sessions::Storable versions through 0.05 for Perl generate session ids insecurely. The default session id generator returns a SHA-1 hash seeded with the built-in rand function, the epoch time, the heap address of an anonymous hash, and the PID. These are predictable or low-entropy sources that are…

Mojolicious::Plugin::Statsd versions through 0.04 for Perl allowed metric injections. The metric names and set values were not checked for newlines, colons or pipes. Metrics generated from untrusted sources could inject additional statsd metrics. Version 0.06 changes the module from being a statsd client to using a…

Mojolicious::Plugin::CaptchaPNG version 1.05 for Perl uses a weak random number source for generating the captcha. That version uses the built-in rand() function for generating the captcha text as well as image noise, which is insecure.

Mojolicious::Plugin::CSRF 1.03 for Perl uses a weak random number source for generating CSRF tokens. That version of the module generates tokens as an MD5 of the process id, the current time, and a single call to the built-in rand() function.

Mojolicious versions from 0.999922 for Perl uses a hard coded string, or the application's class name, as an HMAC session cookie secret by default. These predictable default secrets can be exploited by an attacker to forge session cookies. An attacker who knows or guesses the secret could compute valid HMAC signatures…

Mojolicious versions from 7.28 through 9.45 for Perl will generate weak HMAC session cookie secrets via "mojo generate app" by default. When creating a default app skeleton with the "mojo generate app" tool, a weak secret is written to the application's configuration file using the insecure rand() function, and used…

The Mojolicious module before 9.11 for Perl has a bug in format detection that can potentially be exploited for denial of service.

The Mojolicious module before 8.65 for Perl is vulnerable to secure_compare timing attacks that allow an attacker to guess the length of a secret string. Only versions after 1.74 are affected.

The Mojolicious module before 7.66 for Perl may leak cookies in certain situations related to multiple similar cookies for the same domain. This affects Mojo::UserAgent::CookieJar.

Cross-site scripting (XSS) vulnerability in the link_to helper in Mojolicious before 1.12 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

Mojolicious before 0.999927 does not properly implement HMAC-MD5 checksums, which has unspecified impact and remote attack vectors.

Commands.pm in Mojolicious before 0.999928 does not properly perform CGI environment detection, which has unspecified impact and remote attack vectors.

Unspecified vulnerability in the MojoX::Dispatcher::Static implementation in Mojolicious before 0.991250 has unknown impact and attack vectors.

Directory traversal vulnerability in Path.pm in Mojolicious before 1.16 allows remote attackers to read arbitrary files via a %2f..%2f (encoded slash dot dot slash) in a URI.
