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.

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

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. (CVE-2019-10740)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote SUSE Linux SUSE15 host has a package installed that is affected by multiple vulnerabilities as referenced in the openSUSE-SU-2022:10148-1 advisory.

  - rcube_image.php in Roundcube Webmail before 1.4.4 allows attackers to execute arbitrary code via shell     metacharacters in a configuration setting for im_convert_path or im_identify_path. (CVE-2020-12641)

  - Roundcube Webmail before 1.3.15 and 1.4.8 allows stored XSS in HTML messages during message display via a     crafted SVG document. This issue has been fixed in 1.4.8 and 1.3.15. (CVE-2020-16145)

  - An XSS issue was discovered in Roundcube Webmail before 1.2.13, 1.3.x before 1.3.16, and 1.4.x before     1.4.10. The attacker can send a plain text e-mail message, with JavaScript in a link reference element     that is mishandled by linkref_addindex in rcube_string_replacer.php. (CVE-2020-35730)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
