Hello Team,
I am having this issue after upgrading the Wazuh Manager from any 4.2.x version:

[root@wzh-upg ~]# yum install wazuh-manager-4.2.7-1.x86_64.rpm                                                                 <--- INSTALLING 4.2.x

[root@wzh-upg ~]# find /var/ossec/ -user 997 | wc -l
7

Steps to reproduce

Install any CentOS7 system.
Mount a secondary disk in any mount point
Install Wazuh Manager 4.2.x
Stop the Wazuh Manager service
Move /var/ossec folder to the mount point
Create a symlink for the new location
Start the Wazuh Manager service
Create some custom rules and decoders files and modify some configurations
Upgrade the Wazuh Manager to the v4.3.4 from a package already downloaded.

Evidences

Configuration:

# ls -l /var/ | grep ossec
lrwxrwxrwx.  1 root root   20 Jun 15 16:42 ossec -> /data/staging/ossec/

# /var/ossec/bin/wazuh-control info
WAZUH_VERSION="v4.3.4"
WAZUH_REVISION="40316"
WAZUH_TYPE="server"

Misconfigurations

[root@wzh-upg ~]# find /var/ossec/ -group ossec | wc -l
74
[root@wzh-upg ~]# find /var/ossec/ -user 998 | wc -l
47
[root@wzh-upg ~]# find /var/ossec/ -user 997 | wc -l
7

Conclusion

It seems the use of a symbolic link for the Wazuh Manager folder it breaks the ownership of the files when upgrading.

The text was updated successfully, but these errors were encountered:

dariommr · 2022-06-15T22:10:47Z

Workaround

Find the ID of the ossec users before performing the upgrade:

# cat /etc/passwd | grep ossec
ossec:x:997:118::/var/ossec:/sbin/nologin
ossecm:x:998:118::/var/ossec:/sbin/nologin
ossecr:x:999:118::/var/ossec:/sbin/nologin

Find all users 999, 998 and 997 and replace them with the user wazuh, apply the same but for the group ossec:

[root@wzh-upg ~]# find /var/ossec/ -user 997 -exec chown wazuh {} \;
[root@wzh-upg ~]# find /var/ossec/ -user 998 -exec chown wazuh {} \;
[root@wzh-upg ~]# find /var/ossec/ -user 999 -exec chown wazuh {} \;
[root@wzh-upg ~]# find /var/ossec/ -group ossec -exec chown :wazuh {} \;

Reproducing the issue

This issue was reproduced following the described steps above.

First, we have a fresh CentOS 7 box where Wazuh has been uninstalled and all the groups and users were removed.
This is the content of /etc/passwd and /etc/group files before installing anything, there is no trace of Wazuh or OSSEC

We can see in /etc/group that the ossec:x:994: group wasn't deleted.
Also, the find commands that should update the ownership of the files left some files belonging to the ossec group or user.

Root cause analysis

These changes were introduced in #716: Change default user and group.

Upgrade fails when using symbolic links

This happens because the upgrade script runs the find commands in the following way: the line

find %{_localstatedir} -group ossec -user root -exec chown root:wazuh {} \; > /dev/null 2>&1 || true

Is translated to

+ find /var/ossec -group ossec -user root -exec chown root:wazuh '{}' ';'

But /var/ossec is a symbolic link and we need to add a / character at the end. If we don't, it won't be resolved properly and the find command won't run in the real folder.

This is described here https://pubs.opengroup.org/onlinepubs/9699919799/xrat/V4_xbd_chap03.html#tag_21_03_00_59
When the final component of a pathname is a symbolic link, the standard requires that a trailing <slash> causes the link to be followed. This is the behavior of historical implementations. For example, for /a/b and /a/b/, if /a/b is a symbolic link to a directory, then /a/b refers to the symbolic link, and /a/b/ refers to the directory to which the symbolic link points.

ossec group isn't removed after the upgrade

This happens because there is a bug in the SPECS file for rpm (all distributions should be checked).
Here the script is trying to verify if the ossec group exists using id -g ossec

wazuh-packages/rpms/SPECS/wazuh-manager.spec

Lines 459 to 461 in 1cf85f1

    
           if id -g ossec > /dev/null 2>&1; then 
        
             groupdel ossec > /dev/null 2>&1 
        
           fi

But the correct expression to verify the existence of the group should be getent group ossec. This prevents the ossec group for being removed after the upgrade. We should also verify it here

wazuh-packages/rpms/SPECS/wazuh-manager.spec

Line 445 in 1cf85f1

if id -g ossec > /dev/null 2>&1; then
