AlienVault OTX Vulnerabilities

AlienVault OTX Malware

SAP NetWeaver ABAP Application Server and ABAP Platform do not sufficiently encode user-controlled inputs, resulting in Cross-Site Scripting (XSS) vulnerability. An attacker with low privileges can cause limited impact to confidentiality of the application data after successful exploitation.

CVE-2024-21738 is a Cross-Site Scripting (XSS) vulnerability identified in SAP NetWeaver ABAP Application Server and ABAP Platform, specifically affecting multiple SAP_BASIS versions ranging from 700 through 794. The vulnerability arises due to improper neutralization of user-controlled input during web page generation, meaning that the application does not sufficiently encode or sanitize inputs before reflecting them in web pages. This flaw allows an attacker with low privileges to inject malicious scripts into the web interface, which can then be executed in the context of other users' browsers. The vulnerability is classified under CWE-79, a common weakness related to improper input validation leading to XSS. The CVSS v3.1 base score is 4.1 (medium severity), with vector AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:N/A:N, indicating that the attack can be performed remotely over the network with low attack complexity, requires low privileges, and user interaction is needed. The scope is changed (S:C), meaning the vulnerability affects resources beyond the security scope of the vulnerable component. The impact is limited to confidentiality, with no direct impact on integrity or availability. No known exploits are reported in the wild yet, and no patches or fixes are linked in the provided data, suggesting that remediation may still be pending or in progress. The vulnerability could allow an attacker to steal sensitive information accessible to the victim user, such as session tokens or other confidential data displayed in the affected web interface, potentially leading to further compromise if leveraged in chained attacks. Given the widespread use of SAP NetWeaver in enterprise environments, this vulnerability poses a risk to organizations relying on these SAP versions for critical business processes.
