CVE-2007-0275 : Detail

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

[+] Vulnerability origin: Oracle HTTP Server (OHS) developed by Oracle Corporation is an OracleAS 10g's Web Server component. The vulnerable product is based on the Apache 1.3 Web server. This later is vulnerable to Unfiltered Header Injection which makes the vulnerability’s origin of this OHS version. [+] PoC: See the video in Youtube: http://www.youtube.com/watch?v=cBmbkAYXdjo See the PDF: http://www.yaboukir.com/wp-content/bugtraq/XSS_Header_Injection_in_OHS_by_Yasser.pdf [+] Attack: > Atack Prerequisites for a successful exploitation: Target software must be a client that allows scripting communication from remote hosts. Crafting the attack to exploit this issue is not a complex process. However most of the unsophisticated attackers will not know that such an attack is possible. Also an attacker needs to reach his victims by enticing them to visit remote site of some sort to redirect them and data to. > Attacker Skills or Knowledge Required - Skill or Knowledge Level: Low To achieve a redirection and use of less trusted source, an attacker can simply edit HTTP Headers that are sent to client machine. - Skill or Knowledge Level: High Exploiting a client side vulnerability to inject malicious scripts into the browser's executable process. > Methods of Attack - Injection - Modification of Resources - Protocol Manipulation > Exploit: - Steal session IDs, credentials, page content, etc.: As the attacker succeeds in exploiting the vulnerability, he can choose to steal user's credentials in order to reuse or to analyze them later on. - Forceful browsing: When the attacker targets this Oracle application (through CSRF vulnerabilities, Clickjacking), the user will then be the one who perform the attacks without being aware of it. - Content spoofing: By manipulating the content, the attacker targets the information that the user would like to get from the Website. [+] Solution: A solution to this issue might be the update/upgrade to the Oracle HTTP Server 11g which is based on Apache 2.2. In fact, Oracle supports only the code they ship with the Oracle Application Server 10g. Externally added modules or other changes are not supported. As a matter of fact, security patches from the Apache organization in its latest versions 1.3.35/2.0.58/2.2.2 to this vulnerability onto Oracle HTTP Server should not be applied.
