| In the Linux kernel, the following vulnerability has been resolved:
netfilter: ipset: enforce documented limit to prevent allocating huge memory
Daniel Xu reported that the hash:net,iface type of the ipset subsystem does
not limit adding the same network with different interfaces to a set, which
can lead to huge memory usage or allocation failure.
The quick reproducer is
$ ipset create ACL.IN.ALL_PERMIT hash:net,iface hashsize 1048576 timeout 0
$ for i in $(seq 0 100); do /sbin/ipset add ACL.IN.ALL_PERMIT 0.0.0.0/0,kaf_$i timeout 0 -exist; done
The backtrace when vmalloc fails:
[Tue Oct 25 00:13:08 2022] ipset: vmalloc error: size 1073741848, exceeds total pages
<...>

The fix is to enforce the limit documented in the ipset(8) manpage:
> The internal restriction of the hash:net,iface set type is that the same
> network prefix cannot be stored with more than 64 different interfaces
> in a single set. |
| SAP CommonCryptoLib does not perform necessary boundary checks during pre-authentication parsing of manipulated ASN.1 data over the network. This may result in memory corruption followed by an application crash, hence leading to a high impact on availability. There is no impact on confidentiality or integrity. |
| SAP S/4HANA landscape SAP E-Recruiting BSP allows an unauthenticated attacker to craft malicious links, when clicked the victim could be redirected to the page controlled by the attacker. This has low impact on confidentiality and integrity of the application with no impact on availability. |
| Due to an Information Disclosure vulnerability in SAP NetWeaver Application Server Java, internal metadata files could be accessed via manipulated URLs. An unauthenticated attacker could exploit this vulnerability by inserting arbitrary path components in the request, allowing unauthorized access to sensitive application metadata. This results in a partial compromise of the confidentiality of the information without affecting the integrity or availability of the application server. |
| SAP S4CORE (Manage journal entries) does not perform necessary authorization checks for an authenticated user resulting in escalation of privileges. This has low impact on confidentiality of the application with no impact on integrity and availability of the application. |
| Due to information disclosure vulnerability in anonymous API provided by SAP Business One (SLD), an attacker with normal user access could gain access to unauthorized information. As a result, it has a low impact on the confidentiality of the application but no impact on the integrity and availability. |
| Due to insufficient validation of connection property values, the SAP HANA JDBC Client allows a high-privilege locally authenticated user to supply crafted parameters that lead to unauthorized code loading, resulting in low impact on confidentiality and integrity and high impact on availability of the application. |
| Due to a Path Traversal vulnerability in SAP Business Connector, an attacker authenticated as an administrator with adjacent access could read, write, overwrite, and delete arbitrary files on the host system. Successful exploitation could enable the attacker to execute arbitrary operating system commands on the server, resulting in a complete compromise of the confidentiality, integrity, and availability of the affected system. |
| Due to an Open Redirect vulnerability in SAP Business Connector, an unauthenticated attacker could craft a malicious URL that, if accessed by a victim, redirects them to an attacker-controlled site displayed within an embedded frame. Successful exploitation could allow the attacker to steal sensitive information and perform unauthorized actions, impacting the confidentiality and integrity of web client data. There is no impact to system availability resulting from this vulnerability. |
| Due to an OS Command Injection vulnerability in SAP Business Connector, an authenticated attacker with administrative access and adjacent network access could upload specially crafted content to the server. If processed by the application, this content enables execution of arbitrary operating system commands. Successful exploitation could lead to full compromise of the system�s confidentiality, integrity, and availability. |
| SQL Anywhere Monitor (Non-GUI) baked credentials into the code,exposing the resources or functionality to unintended users and providing attackers with the possibility of arbitrary code execution.This could cause high impact on confidentiality integrity and availability of the system. |
| SAP Starter Solution allows an authenticated attacker to execute crafted database queries, thereby exposing the back-end database. As a result, this vulnerability has a low impact on the application's confidentiality and integrity but no impact on its availability. |
| SAP GUI for Windows may allow a highly privileged user on the affected client PC to locally access sensitive information stored in process memory during runtime.This vulnerability has a high impact on confidentiality, with no impact on integrity and availability. |
| Due to missing input sanitation, SAP Solution Manager allows an authenticated attacker to insert malicious code when calling a remote-enabled function module. This could provide the attacker with full control of the system hence leading to high impact on confidentiality, integrity and availability of the system. |
| Due to a Reflected Cross-Site Scripting (XSS) vulnerability in SAP Business Connector, an unauthenticated attacker could generate a malicious link and make it publicly accessible. If an authenticated victim accesses this link, the injected input is processed during web page generation, resulting in the execution of malicious content in the victim's browser context. This could allow the attacker to access or modify information within the victim�s browser scope, impacting confidentiality and integrity, while availability remains unaffected |
| Due to missing authentication, SAP HANA 2.0 (hdbrss) allows an unauthenticated attacker to call a remote-enabled function that will enable them to view information. As a result, it has a low impact on the confidentiality but no impact on the integrity and availability of the system. |
| SAP NetWeaver Enterprise Portal allows an unauthenticated attacker to inject JNDI environment properties or pass a URL used during JNDI lookup operations, enabling access to an unintended JNDI provider.�This could further lead to disclosure or modification of information about the server. There is no impact on availability. |
| Migration Workbench (DX Workbench) in SAP NetWeaver Application Server for ABAP fails to trigger a malware scan when an attacker with administrative privileges uploads files to the application server. An attacker could leverage this and upload a malicious file into the system. This results in a low impact on the integrity of the application. |
| Due to a missing authorization check in SAP NetWeaver Application Server for ABAP, an authenticated attacker with basic privileges could execute a specific function module in ABAP to retrieve restricted technical information from the system. This disclosure of environment details of the system could further assist this attacker to plan subsequent attacks. As a result, this vulnerability has a low impact on confidentiality, with no impact on the integrity or availability of the application. |
| In TEE EcDSA algorithm, there is a possible memory consistency issue. This could lead to generated incorrect signature results with low probability. |
