Description

This security bulletin contains information about 8 secuirty vulnerabilities.


1) Buffer overflow (CVE-ID: CVE-2019-13273)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in the csvinfo CGI script A remote attacker can send a specially crafted GET request that triggers an sprintf of the "srcdb" parameter, trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


2) Cross-site scripting (CVE-ID: CVE-2019-13274)

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists in the csvinfo CGI script due to insufficient sanitization of user-supplied data passed via the "db" parameter. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.


3) Buffer overflow (CVE-ID: CVE-2019-13451)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in the "history.c". A remote attacker can trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


4) Stack-based buffer overflow (CVE-ID: CVE-2019-13455)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in the alert acknowledgment CGI tool because of expansion in "acknowledge.c". A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


5) Buffer overflow (CVE-ID: CVE-2019-13484)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in the status-log viewer CGI because of   expansion in the "appfeed.c". A remote attacker can trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


6) Stack-based buffer overflow (CVE-ID: CVE-2019-13486)

The vulnerability allows a remote attacker to access or modify data, or cause a denial of service (DoS) condition on an affected system.

The vulnerability exists in the status-log viewer component due to a boundary error in the "svcstatus.c" file because the software does not properly validate user-supplied input. A remote unauthenticated attacker can submit malicious input, trigger stack-based buffer overflow and access or modify data, or cause a DoS condition on the affected system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


7) Stack-based buffer overflow (CVE-ID: CVE-2019-13485)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when processing a long hostname or service parameter in history.c within the in the history viewer component. A remote authenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


8) Buffer overflow (CVE-ID: CVE-2019-13452)

The vulnerability allows a remote attacker to cause a denial of service (DoS) condition on the target system.

The vulnerability exists due to insufficient validation of user-supplied input in the "reportlog.c" file. A remote attacker can submit malicious input, trigger memory corruption and cause a denial of service condition on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
