TA0009Collection
Adversaries may stage collected data in a central location or directory prior to Exfiltration. Data may be kept in separate files or combined into one file through techniques such as [Archive Collected Data](https://attack.mitre.org/techniques/T1560). Interactive command shells may be used, and common functionality within [cmd](https://attack.mitre.org/software/S0106) and bash may be used to copy data into a staging location.(Citation: PWC Cloud Hopper April 2017) In cloud environments, adversaries may stage data within a particular instance or virtual machine before exfiltration. An adversary may [Create Cloud Instance](https://attack.mitre.org/techniques/T1578/002) and stage data in that instance.(Citation: Mandiant M-Trends 2020) Adversaries may choose to stage data from a victim network in a centralized location prior to Exfiltration to minimize the number of connections made to their C2 server and better evade detection.

CVE-2014-6278

GNU Bash through 4.3 bash43-026 does not properly parse function definitions in the values of environment variables, which allows remote attackers to execute arbitrary commands via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-6271, CVE-2014-7169, and CVE-2014-6277.

CVE-2026-105134

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.

CVE-2023-22894

Strapi through 4.5.5 allows attackers (with access to the admin panel) to discover sensitive user details by exploiting the query filter. The attacker can filter users by columns that contain sensitive information and infer a value from API responses. If the attacker has super admin access, then this can be exploited to discover the password hash and password reset token of all users. If the attacker has admin panel access to an account with permission to access the username and email of API users with a lower privileged role (e.g., Editor or Author), then this can be exploited to discover sensitive information for all API users but not other admin accounts.
