View DetailsCWE-49: Path Equivalence: 'filename/' (Trailing Slash) is a Common Weakness Enumeration (CWE) entry maintained by MITRE. The product accepts path input in the form of trailing slash ('filedir/') without appropriate validation, which can lead to ambiguous path resolution and allow an attacker to traverse the file system to unintended locations or access arbitrary files.
If exploited, CWE-49 (Path Equivalence: 'filename/' (Trailing Slash)) it can compromise Confidentiality and Integrity, leading to outcomes such as Read Files or Directories and Modify Files or Directories.
CWE-49 commonly affects Not Language-Specific. Note that weaknesses are often language-agnostic patterns, so secure coding practices apply broadly.
MITRE documents real CVEs mapped to CWE-49, including CVE-2002-0253, CVE-2001-0446, CVE-2004-0334, CVE-2001-0893 and CVE-2001-0892. You can look up the full details of each CVE, including CVSS scores and remediation guidance, on our CVE Lookup tool.
A CWE (Common Weakness Enumeration) like CWE-49 describes a category of software weakness — the underlying flaw type. A CVE (Common Vulnerabilities and Exposures) identifies a specific, real-world vulnerability in a particular product. In short, a CWE is the kind of mistake, and a CVE is an instance of that mistake being found in software.
