Ahsay AhsayCBS Replication Receiver UpdateReceivers.do os command injection

Noroxi assessment

Priority: This week (action score 78/100)

  • CISA has confirmed exploitation in the wild (Oct 14, 2026). Remediation deadline for US federal agencies: Oct 17, 2026.
  • Probability of exploitation in the next 30 days: 38.3% (FIRST EPSS); higher than 98.5% of all records.
  • This probability rose by 34 points in the last 7 days.
  • 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: Ahsay AhsayCBS 10.3.4.

Don’t wait for the next maintenance window. Upgrade to Ahsay AhsayCBS 10.3.4 or later.

Primary sources: NVD · CVE.org · CISA KEV · FIRST EPSS

A flaw has been found in Ahsay AhsayCBS up to 10.3.2. This vulnerability affects unknown code of the file /rps/api/json/UpdateReceivers.do of the component Replication Receiver. Executing a manipulation of the argument random can lead to os command injection. It is possible to launch the attack remotely. The exploit has been published and may be used. Upgrading to version 10.3.4 is able to resolve this issue. Upgrading the affected component is advised.
