SugarCRM <= 9.0.1 Multiple Phar Deserialization Vulnerabilities
---------------------------------------------------------------
[-] Software Link:
https://www.sugarcrm.com
[-] Affected Versions:
Version 9.0.1 and prior versions, 8.0.3 and prior versions.
[-] Vulnerabilities Description:
1) User input passed through the "backup_dir" parameter when handling
the
"Backups" action within the "Administration" module is not properly
sanitized
before being used in a file operation. This can be exploited by
malicious users
to inject arbitrary PHP objects into the application scope (PHP Object
Injection
via phar:// stream wrapper), allowing them to carry out a variety of
attacks,
such as executing arbitrary PHP code. Successful exploitation of this
vulnerability requires a System Administrator account.
2) User input passed through the "file_name" parameter when handling the
"step3"
action within the "Import" module is not properly sanitized before being
used in
a file operation. This can be exploited by malicious users to inject
arbitrary
PHP objects into the application scope (PHP Object Injection via phar://
stream
wrapper), allowing them to carry out a variety of attacks, such as
executing
arbitrary PHP code.
3) User input passed through the "importFile" parameter when handling
the
"RefreshMapping" action within the "Import" module is not properly
sanitized
before being used in a file operation. This can be exploited by
malicious users
to inject arbitrary PHP objects into the application scope (PHP Object
Injection
via phar:// stream wrapper), allowing them to carry out a variety of
attacks,
such as executing arbitrary PHP code.
4) User input passed through the "load_module_from_dir" parameter when
handling
the "UpgradeWizard" action within the "Administration" module is not
properly
sanitized before being used in a file operation. This can be exploited
by malicious
users to inject arbitrary PHP objects into the application scope (PHP
Object
Injection via phar:// stream wrapper), allowing them to carry out a
variety of
attacks, such as executing arbitrary PHP code. Successful exploitation
of this
vulnerability requires a System Administrator account.
5) User input passed through the "file_name" parameter when handling the
"UploadFileCheck" action within the "UpgradeWizard" module is not
properly
sanitized before being used in a file operation. This can be exploited
by
malicious users to inject arbitrary PHP objects into the application
scope
(PHP Object Injection via phar:// stream wrapper), allowing them to
carry
out a variety of attacks, such as executing arbitrary PHP code.
