Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Command injection
EUVDB-ID: #VU10897
Risk: Low
CVSSv4.0: 9.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Clear]
CVE-ID: CVE-2018-0147
CWE-ID:
CWE-77 - Command injection
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary commands on the target system.
The weakness exists in Java deserialization due to insecure deserialization of user-supplied content. A remote attacker can send a specially crafted serialized Java object and execute arbitrary commands on the device with root privileges.
MitigationUpdate to version 5.8 patch 9.
Vulnerable software versionsCisco Secure Access Control: 5.2.0.3
CPE2.3 External linkshttps://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180307-acs2
Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
How the attacker can exploit this vulnerability?
The attacker would have to send a specially crafted request to the affected application in order to exploit this vulnerability.
Is there known malware, which exploits this vulnerability?
Yes. This vulnerability is being exploited in the wild.
2) XXE attack
EUVDB-ID: #VU10902
Risk: Low
CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2018-0218
CWE-ID:
CWE-611 - Improper Restriction of XML External Entity Reference ('XXE')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to conduct XXE attack.
The weakness exists in the web-based user interface due to improper handling of XML External Entities (XXEs) when parsing an XML file. A remote attacker can trick the administrator of an affected system to import a crafted XML file, perform XXE attack and read arbitrary data.
Update to version 5.8 patch 9.
Vulnerable software versionsCisco Secure Access Control: 5.8.0.8
