A valuable source for these insights is the product use phase. In practice, product planners are often forced to work with assumptions and speculations as insights from the use phase are insufficiently identified and documented. A new opportunity to address this problem arises from the ongoing digitalization that enables products to generate and collect data during their utilization. Analyzing these data could enable their manufacturers to generate and exploit insights concerning product performance and user behavior, revealing problems and potentials for improvement. However, research on analyzing use phase data in product planning of manufacturing companies is scarce. Therefore, we conducted an exploratory interview study with decision-makers of eight manufacturing companies. The result of this paper is a detailed description of the potentials and challenges that the interviewees associated with analyzing use phase data in product planning. The potentials explain the intended purpose and generic application examples. The challenges concern the products, the data, the customers, the implementation, and the employees. By gathering the potentials and challenges through expert interviews, our study structures the topic from the perspective of the potential users and shows the needs for future research."}],"publication":"Artificial Intelligence for Engineering Design, Analysis and Manufacturing","type":"journal_article","language":[{"iso":"eng"}],"keyword":["Artificial Intelligence","Industrial and Manufacturing Engineering"],"article_number":"e14","department":[{"_id":"563"}],"user_id":"15782","_id":"30193","intvolume":"        36","citation":{"ama":"Meyer M, Fichtler T, Koldewey C, Dumitrescu R.

This technique, based on rebuilding the instance of objects from serialized byte streams, can be dangerous since it can open the application to attacks such as remote code execution (RCE) if the data to deserialize is originating from an untrusted source. Deserialization vulnerabilities are so critical that they are in OWASP’s list of top 10 security risks for web applications. This is mainly caused by faults in the development process of applications and by flaws in their dependencies, i.e., flaws in the libraries used by these applications. No previous work has studied deserialization attacks in-depth: How are they performed? How are weaknesses introduced and patched? And for how long are vulnerabilities present in the codebase? To yield a deeper understanding of this important kind of vulnerability, we perform two main analyses: one on attack gadgets, i.e., exploitable pieces of code, present in Java libraries, and one on vulnerabilities present in Java applications. For the first analysis, we conduct an exploratory large-scale study by running 256 515 experiments in which we vary the versions of libraries for each of the 19 publicly available exploits. Such attacks rely on a combination of\r\n            <jats:italic>gadgets</jats:italic>\r\n            present in one or multiple Java libraries. A gadget is a method which is using objects or fields that can be attacker-controlled. Our goal is to precisely identify library versions containing gadgets and to understand how gadgets have been introduced and how they have been patched. We observe that the modification of one innocent-looking detail in a class – such as making it\r\n            <jats:monospace>public</jats:monospace>\r\n            – can already introduce a gadget. Furthermore, we noticed that among the studied libraries, 37.5% are not patched, leaving gadgets available for future attacks.\r\n          </jats:p>\r\n          <jats:p>For the second analysis, we manually analyze 104 deserialization vulnerabilities CVEs to understand how vulnerabilities are introduced and patched in real-life Java applications. Results indicate that the vulnerabilities are not always completely patched or that a workaround solution is proposed. With a workaround solution, applications are still vulnerable since the code itself is unchanged.</jats:p>"}],"status":"public","publication":"ACM Transactions on Software Engineering and Methodology","type":"journal_article","title":"An In-depth Study of Java Deserialization Remote-Code Execution Exploits and Vulnerabilities","doi":"10.1145/3554732","publisher":"Association for Computing Machinery (ACM)","date_updated":"2022-10-20T12:32:31Z","date_created":"2022-10-20T12:31:49Z","author":[{"full_name":"Sayar, Imen","last_name":"Sayar","first_name":"Imen"},{"full_name":"Bartel, Alexandre","last_name":"Bartel","first_name":"Alexandre"},{"id":"59256","full_name":"Bodden, Eric","last_name":"Bodden","orcid":"0000-0003-3470-3647","first_name":"Eric"},{"full_name":"Le Traon, Yves","last_name":"Le Traon","first_name":"Yves"}],"year":"2022","citation":{"apa":"Sayar, I., Bartel, A., Bodden, E., &#38; Le Traon, Y.

Sparsity is an important feature to ensure robustness against noisy data, but also to find models that are interpretable and easy to analyze due to the small number of relevant terms. It is common practice to enforce sparsity by adding the ℓ1-norm as a weighted penalty term. In order to gain a better understanding and to allow for an informed model selection, we directly solve the corresponding multiobjective optimization problem (MOP) that arises when we minimize the main objective and the ℓ1-norm simultaneously. As this MOP is in general non-convex for nonlinear objectives, the weighting method will fail to provide all optimal compromises. To avoid this issue, we present a continuation method which is specifically tailored to MOPs with two objective functions one of which is the ℓ1-norm. Our method can be seen as a generalization of well-known homotopy methods for linear regression problems to the nonlinear case. Several numerical examples - including neural network training - demonstrate our theoretical findings and the additional insight that can be gained by this multiobjective approach."}],"language":[{"iso":"eng"}],"ddc":["510"],"issue":"11","year":"2022","date_created":"2020-12-15T07:46:36Z","publisher":"IEEE","title":"On the Treatment of Optimization Problems with L1 Penalty Terms via Multiobjective Continuation","type":"journal_article","status":"public","user_id":"47427","department":[{"_id":"101"},{"_id":"530"},{"_id":"655"}],"_id":"20731","file_date_updated":"2021-09-25T11:59:15Z","article_type":"original","publication_status":"epub_ahead","has_accepted_license":"1","citation":{"chicago":"Bieker, Katharina, Bennet Gebken, and Sebastian Peitz. “On the Treatment of Optimization Problems with L1 Penalty Terms via Multiobjective Continuation.” <i>IEEE Transactions on Pattern Analysis and Machine Intelligence</i> 44, no. 11 (2022): 7797–7808. <a href=\"https://doi.org/10.1109/TPAMI.2021.3114962\">https://doi.org/10.1109/TPAMI.2021.3114962</a>.","ieee":"K.

As previous studies did not conduct a qualitative examination of the validity and severity of the findings, our objective was to understand the findings in more depth. We analyzed a set of 936 open-source Java applications for cryptographic misuses. Our study reveals that 88.10 % of the analyzed applications fail to use cryptographic APIs securely. Through our manual analysis of a random sample, we gained new insights into effective false positives. For example, every fourth misuse of the frequently misused JCA class MessageDigest is an effective false positive due to its occurrence in a non-security context. As we wanted to gain deeper insights into the security implications of these misuses, we created an extensive vulnerability model for cryptographic API misuses. Our model includes previously undiscussed attacks in the context of cryptographic APIs such as DoS attacks. This model reveals that nearly half of the misuses are of high severity, e.g., hard-coded credentials and potential Man-in-the-Middle attacks.","lang":"eng"}]},{"status":"public","editor":[{"last_name":"Milani","full_name":"Milani, Alessia","first_name":"Alessia"},{"first_name":"Philipp","last_name":"Woelfel","full_name":"Woelfel, Philipp"}],"type":"conference","publication":"PODC ’22: ACM Symposium on Principles of Distributed Computing, Salerno, Italy, July 25 - 29, 2022","language":[{"iso":"eng"}],"user_id":"15504","department":[{"_id":"79"}],"project":[{"_id":"1","name":"SFB 901: SFB 901"},{"name":"SFB 901 - A: SFB 901 - Project Area A","_id":"2"},{"_id":"5","name":"SFB 901 - A1: SFB 901 - Subproject A1"}],"_id":"33967","citation":{"mla":"Aguiliera, Marcos, et al. “2022 Edsger W.
