CVE-2020-12641: rcube_image.php in Roundcube Webmail before 1.4.4 allows attackers to execute arbitrary code via shell metacharacters in a configuration set

Noroxi assessment

Priority: Now (action score 94/100)

CISA has confirmed exploitation in the wild (Jun 22, 2023). Remediation deadline for US federal agencies: Jul 13, 2023.
A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
Probability of exploitation in the next 30 days: 84.3% (FIRST EPSS); higher than 99.6% of all records.
Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
According to CISA the attack is automatable: targets can be found by mass scanning.
Fixed version: roundcube (Debian:12) 1.4.4+dfsg.1-1; roundcubemail (openSUSE:Leap 15.1) 1.3.15-bp152.4.3.1; roundcubemail (openSUSE:Leap 15.3) 1.5.3-bp154.2.3.1.
Mentioned 2 times in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Patch today or shut off access. Upgrade to roundcube (Debian:12) 1.4.4+dfsg.1-1; roundcubemail (openSUSE:Leap 15.1) 1.3.15-bp152.4.3.1; roundcubemail (openSUSE:Leap 15.3) 1.5.3-bp154.2.3.1 or later.
