Description

A flaw has been found in Ahsay AhsayCBS up to 9.15.2.69/10.3.4.44. 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 9.15.2.70 and 10.3.4.45 is able to resolve this issue. Upgrading the affected component is advised. The initial patch did not fix the security vulnerability properly. An update of the CVE entry to reflect this became necessary.

CVSS measures how bad exploitation would be; EPSS estimates how likely exploitation is within 30 days; the CISA listing means it is already happening. Read them together: a CVSS 9.8 with EPSS 0.04% is usually less urgent than a CVSS 7.2 on the exploited list. Data: NVD, FIRST EPSS, CISA KEV; detail is cached for a week, scores for a day. ATT&CK techniques come from the CTID KEV mappings project where a curated mapping exists, otherwise they are inferred from the weakness class and labelled as such.
