Symfony is a PHP framework for web and console applications and a set of reusable PHP components. The Symfony HTTP cache system, acts as a reverse proxy: It caches entire responses (including headers) and returns them to the clients. In a recent change in the `AbstractSessionListener`, the response might contain a `Set-Cookie` header. If the Symfony HTTP cache system is enabled, this response might bill stored and return to the next clients. An attacker can use this vulnerability to retrieve the victim's session. This issue has been patched and is available for branch 4.4.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

The remote Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7272-1 advisory.

    Soner Sayakci discovered that Symfony incorrectly handled cookie storage in the web cache. An attacker     could possibly use this issue to obtain sensitive information and access unauthorized resources.
    (CVE-2022-24894)

    Marco Squarcina discovered that Symfony incorrectly handled the storage of user session information. An     attacker could possibly use this issue to perform a cross-site request forgery (CSRF) attack.
    (CVE-2022-24895)

    Pierre Rudloff discovered that Symfony incorrectly checked HTML input. An attacker could possibly use this     issue to perform cross site scripting. (CVE-2023-46734)

    Vladimir Dusheyko discovered that Symfony incorrectly sanitized special input with a PHP directive in URL     query strings. An attacker could possibly use this issue to expose sensitive information or cause a denial     of service. This issue only affected Ubuntu 24.04 LTS and Ubuntu 22.04 LTS. (CVE-2024-50340)

    Oleg Andreyev, Antoine Makdessi, and Moritz Rauch discovered that Symfony incorrectly handled user     authentication. An attacker could possibly use this issue to access unauthorized resources and expose     sensitive information. This issue was only addressed in Ubuntu 24.04 LTS. (CVE-2024-50341, CVE-2024-51996)

    Linus Karlsson and Chris Smith discovered that Symfony returned internal host information during host     resolution. An attacker could possibly use this issue to obtain sensitive information. This issue only     affected Ubuntu 24.04 LTS and Ubuntu 22.04 LTS. (CVE-2024-50342)

    It was discovered that Symfony incorrectly parsed user input through regular expressions. An attacker     could possibly use this issue to expose sensitive information. (CVE-2024-50343)

    Sam Mush discovered that Symfony incorrectly parsed URIs with special characters. An attacker could     possibly use this issue to perform phishing attacks. (CVE-2024-50345)

    Package        : symfony     Version        : 3.4.22+dfsg-2+deb10u2     CVE ID         : CVE-2021-21424 CVE-2022-24894 CVE-2022-24895

    Multiple security vulnerabilities were found in symfony, a PHP framework     for web and console applications and a set of reusable PHP components,     which could lead to information disclosure or impersonation.

    CVE-2021-21424

        James Isaac, Mathias Brodala and Laurent Minguet discovered that it         was possible to enumerate users without relevant permissions due to         different exception messages depending on whether the user existed         or not.  It was also possible to enumerate users by using a timing         attack, by comparing time elapsed when authenticating an existing         user and authenticating a non-existing user.

        403s are now returned whether the user exists or not if a user         cannot switch to a user or if the user does not exist.

    CVE-2022-24894

        Soner Sayakci discovered that when the Symfony HTTP cache system is         enabled, the response header might be stored with a `Set-Cookie`         header and returned to some other clients, thereby allowing an         attacker to retrieve the victim's session.

        The `HttpStore` constructor now takes a parameter containing a list         of private headers that are removed from the HTTP response headers.
        The default value for this parameter is `Set-Cookie`, but it can be         overridden or extended by the application.

    CVE-2022-24895

        Marco Squarcina discovered that CSRF tokens aren't cleared upon         login, which could enable same-site attackers to bypass the CSRF         protection mechanism by performing an attack similar to a         session-fixation.

    For Debian 10 buster, these problems have been fixed in version     3.4.22+dfsg-2+deb10u2.

    We recommend that you upgrade your symfony packages.
