Exploit of the week
We at CERTStation Labs have selected an exploit that has been released for Microsoft Internet Explorer. The exploit which we had selected acts as a web server that generates an exploit to target vulnerability (CVE-2010-0249) in Internet Explorer. Exploit is written in python and spawns the calculator when it's get executed. After given a port while running it will wait for incoming connection and when target host comes to the attacker site it will send exploit code to the browser and will execute a payload which is calculated here. Attackers can also exploit this issue to execute arbitrary code in the context of the user running the browser. Successful exploits will compromise the application and possibly the computer. Failed attacks will cause denial-of-service conditions.
 
Security tool of the week
The security tool of the week selected by CERTStation Labs is Ncrack. Ncrack is a high-speed network authentication cracking tool. It was built to help companies secure their networks by pro-actively testing all their hosts and networking devices for poor passwords. Security professionals also rely on Ncrack when auditing their clients. Ncrack was designed using a modular approach, a command-line syntax similar to Nmap and a dynamic engine that can adapt its behavior based on network feedback. It allows for rapid, yet reliable large-scale auditing of multiple hosts.
 
The website selected this week by CERTStation Labs is http://wepawet.iseclab.org . WEPAWET is a service for detecting and analyzing web-based malware. It currently handles Flash and JavaScript. WEPAWET runs various analyses on the URLs or files that you submit. At the end of the analysis phase, it tells you whether the resource is malicious or benign and provides you with information that helps you understand why it was classified in a way or the other.

Mon, Feb 08 2010
Geo++ GNCASTER 1.4.0.7 and earlier are prone to authentication bypass vulnerability. The issue occurs as the server generates a nonce for HTTP Digest authentication and utilizes the same nonce for all other authentication until it is restarted. This could be exploited by remote attackers to hijack web sessions or bypass authentication via a replay attack.
Severity

Integer underflow vulnerability has been discovered in IRCD-hybrid, versions 7.2.2 and 7.2.3, ircd-ratbox before 2.2.9, and oftc-hybrid before 1.6.8. The vulnerability is triggered due to the boundary condition error exists in "clean_string" function used in 'irc_string.c' script when processing the "LINKS" command. Exploitation of this vulnerability requires that "flatten_links" is disabled. This could permit a remote attacker to cause the daemon to crash, creating a denial of service condition or execute arbitrary code on a vulnerable system.
Severity
Sun, Feb 07 2010
A vulnerability has been discovered in ircd-ratbox before 2.2.9. The vulnerability is triggered due to a NULL pointer dereference error in 'cache.c' script when processing the "HELP" command. This could be exploited by a remote attacker to cause the daemon to crash, creating a denial of service condition.
Severity
Wed, Feb 03 2010
Apache HTTP Server before 1.3.42 on 64-bit platforms are prone to integer overflow vulnerability. The issue occurs due to improper processing of a large chunk size that triggers a heap-based buffer overflow in the "ap_proxy_send_fb" function in 'proxy/proxy_util.c' script in 'mod_proxy'. This could allow remote origin servers to cause a denial of service (daemon crash) or possibly execute arbitrary code.
Severity
Mon, Feb 08 2010
Asterisk Open Source before 1.6.0.22, 1.6.1.14, and 1.6.2.2; and Business Edition before C.3.3.2 are prone to a denial of service (DoS) vulnerability. The issue occurs due to improper handling of T.38 negotiations over SIP with a negative or overly large value in the "FaxMaxDatagram" field or without any "FaxMaxDatagram" field. This could be exploited by a remote attacker to rash a vulnerable server, creating a denial of service condition.
Severity
Mon, Feb 08 2010
A vulnerability has been discovered in IRCD-Hybrid (aka Hybrid2 IRC Services), version 1.9.2 to 1.9.4. The vulnerability is triggered due to an input validation error in 'mystring.c' used in hybserv when processing private messages. This could be exploited by a remote attacker to cause the service to crash by sending a specially-crafted private message containing ":help t" to the MemoServ service, creating a denial of service condition.
Severity
Sat, Feb 06 2010
Multiple unspecified vulnerabilities have been discovered in Xerox WorkCentre, version 5632, 5638, 5645, 5655, 5665, 5675, and 5687. The issue is triggered due to access validation error in the Network Controller and Web Server which allows bypass "Scan to Mailbox" authorization and web server authorization. Exploitation of the vulnerability require that the user must interact with the attack mechanism. This could allow remote attackers to access mailboxes and read device configuration information.
Severity
Sat, Feb 06 2010
A vulnerability has been discovered in Microsoft Internet Explorer, versions 5.01 SP4, 6, 6 SP1, 7, and 8. The vulnerability is triggered due to the design error exists in the application which does not prevent rendering of non-HTML local files as HTML documents. This remotely exploitable vulnerability requires persuading user into opening a Web site and permit attackers to bypass access restrictions and read arbitrary files via vectors involving JavaScript exploit code that constructs a reference to a file://127.0.0.1 URL, aka the dynamic OBJECT tag vulnerability, as demonstrated by obtaining the data from an "index.dat" file.

A vulnerability has been discovered in Microsoft Internet Explorer, versions 5.01 SP4, 6, 6 SP1, 7, and 8. The vulnerability is triggered due to the design error exists in the application which does not prevent rendering of non-HTML local files as HTML documents. This remotely exploitable vulnerability requires persuading user into opening a Web site and permit attackers to bypass access restrictions and read arbitrary files via vectors involving the product's use of 'text/html' as the default content type for files that are encountered after a redirection, aka the URLMON sniffing vulnerability.
Severity
Sat, Feb 06 2010
A vulnerability has been discovered in IBM WebSphere Commerce, version 7.0. The vulnerability is triggered due to an error in the application which provide weaker than expected security when using a single merchant key provided by the administrator for session and data encryption. This could be exploited by a remote attacker to compromise the integrity of WebSphere Commerce sites.

Tips of the week
Encrypt Data Communication
Securing your Linux server is important to protect your data, intellectual property, and time, from the hands of an attacker. People save important documents online, thinking it's safe to place those documents online. Unless it is transmitted via the Internet using encrypted session, anyone may sniff the data transmitted over the local network. One of tips of the week is to find tools to send or upload important data using encrypted sessions.
Minimize Softwares to Minimize Vulnerabilities
Do we really need all sort of services installed on servers? The answer is NO, we don't. Avoiding the installation of all unnecessary software to provide a safe environment on servers is one of the ways to prevent from being attacked. Another tip of the week is to use a package manager such as "rpm", "dpkg" etc to review all installed set of software packages on servers and delete all unwanted packages.
Disable root Login
Never allow a remote user to login or execute anything on server with root user initially. Users should use sudo to execute root level commands as and when required. Sudo does greatly enhance the security of the system without sharing root password with other users and admins. Sudo also provides simple auditing and tracking features too. Last tip of the week is to disable root login on OpenSSH service and create normal users to login and then issue sudo to execute commands requiring root user's privileges or su - to login as root.
