PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server.
It was found that PHP did not properly handle file names with a NULL character. A remote attacker could possibly use this flaw to make a PHP script access unexpected files and bypass intended file system access restrictions. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2006-7243 to this issue.
A flaw was found in PHP's SSL client's hostname identity check when handling certificates that contain hostnames with NULL bytes. If an attacker was able to get a carefully crafted certificate signed by a trusted Certificate Authority, the attacker could use the certificate to conduct man-in-the-middle attacks to spoof SSL servers. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2013-4248 to this issue.
It was found that the PHP SOAP parser allowed the expansion of external XML entities during SOAP message parsing. A remote attacker could possibly use this flaw to read arbitrary files that are accessible to a PHP application using a SOAP extension. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2013-1643 to this issue.

Recommended Actions for System Products:
Avaya strongly recommends following the
networking and security best practices by implementing
firewalls, ACLs, physical security or other appropriate
access restrictions. Though Avaya believes such
restrictions should always be in place, risk to Avaya
products and the surrounding network from this potential
vulnerability may be mitigated by ensuring these
practices are implemented until such time as an Avaya provided
product update or the recommended Avaya action is applied.
Further restrictions as deemed necessary based on the
customer's security policies may be required during this
interim period, but the System Product operating system or
application should not be modified unless the change is
approved by Avaya.
Making changes that are not approved may void the Avaya product service contract.
When determining risk, Avaya takes into account many factors as outlined by Avaya's Security Vulnerability Classification Policy. The following table describes factors that mitigate the risk of specific vulnerabilities for affected Avaya products:
| Vulnerability | Mitigating Factors |
|---|---|
|
CVE-2006-7243 CVE-2013-1643 CVE-2013-4248 |
These are a Medium risk because only authenticated users could potentially access restricted files or install a malicious certificate. |
Avaya software-only products operate on general-purpose operating systems. Occasionally vulnerabilities may be discovered in the underlying operating system or applications that come with the operating system. These vulnerabilities often do not impact the software-only product directly but may threaten the integrity of the underlying platform.
In the case of this advisory Avaya software-only products are not affected by the vulnerability directly but the underlying Linux platform may be. Customers should determine on which Linux operating system the product was installed and then follow that vendor's guidance.
