CVSS Release: version 2
CVE-2006-3016: Unspecified vulnerability in session.c in PHP before 5.1.3 has unknown impact and attack vectors, related to "certain characters in session names," including special characters that are frequently associated with CRLF injection, SQL injection, cross-site scripting (XSS), and HTTP response splitting vulnerabilities. NOTE: while the nature of the vulnerability is unspecified, it is likely that this is related to a violation of an expectation by PHP applications that the session name is alphanumeric, as implied in the PHP manual for session_name().
The exploitability of CVE-2006-3016 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
Moderate complexity but no authentication required makes CVE-2006-3016 a potential risk.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2006-3016, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2006-3016, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
The EPSS score estimates the probability that this vulnerability will be exploited in the near future.
EPSS Score: 1.39% (probability of exploit)
EPSS Percentile: 86.49%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 13.510000000000005% of others.
