Symphony process is a module for the Symphony PHP framework which executes commands in sub-processes. When consuming a persisted remember-me cookie, Symfony does not check if the username persisted in the database matches the username attached with the cookie, leading to authentication bypass. This vulnerability is fixed in 5.4.47, 6.4.15, and 7.1.8.

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)
